Text A. Energy

Energy is power, both materially and politically, so we should all be interested in who controls our planet's finite resources. But it isn't enough just to find out who is controlling energy supplies and why. We have to understand energy itself.

We use energy every day. It surrounds us in different forms, such as light, heat and electricity. Our bodies use energy stored in molecules of substances to move, breath, grow and think. We also use energy to do work and to play. Humans have invented thousands of machines that use energy to make our work easier, to heat our homes and to get ourselves from place to place. Some of these machines use electricity, while others, like automobiles, use the energy stored in substances such as gasoline.

The two most common forms of energy we use are heat and electricity. Heat is the energy of moving particles in any substance. Electricity is the energy of electrons moving along a conductor like a copper electric wire. Besides heat and electricity we use other forms of energy every day: light, radio waves, sound. Energy is easily converted from one form to another. This is its important and very useful property.

Our mission is to preserve the planet, using less energy that saves natural resources like oil and coal and helps to reduce air pollution.

People are energy rich today. Scientists and inventors discovered ways to use energy to make our lives easier. We should be taught theoretical and practical basics of renewable energy and look for solar, wind, biomass, geothermal and small hydro sources for electricity. A big step has been made by planning ocean-based power plants, which use the energy of waves, sea current and tides. There is a lot of research to be done but there is a usable potential much higher than the entire world's energy consumption.

Text B. Energy sector in Ukraine

The energy sector is of key importance for the national economic development, as both production and municipal facilities require electric power for their operation. The energy sector peculiarity is that the technological equipment and primary generators of electric energy are separated from consumers. As a result, power generation, transmission and distribution have become separate industries. Large energy operations have been established in Ukraine, and energy companies make up the Power Grid of Ukraine. The latter is connected with power systems of Western and Central European countries including Russia, Moldova, Belarus. Three types of generation facilities are operated in Ukraine, including thermal power plants (steam turbine and diesel types), hydroelectric plants( hydroelectric power and hydroelectric accumulating plants) and nuclear power plants. The role of wind and helium power plants is growing.

At present, the situation in the energy sector is characterized by the following parameters: the total capacity of all Ukrainian power plants exceeds 53 million kW, including 34.8 million kW (65.3%) at thermal plants, 13.8 million kW (25.9%) at nuclear plants and 4.7 million kW (8.8%) at hydroelectric plants. Hydropower has a long tradition but there are still some innovations done in the last few years that help our homes become more energy efficient. Power resources of Ukraine are mainly formed by domestic generation capacities (nearly 98%), with the import share being insignificant (2%). The power is largely consumed inside the country (97%), with a small part exported (3%).

Ukraine operates five nuclear power plants, including the Zaporizhzhya, South-Ukrainian, Rivne, Khmelnytsky, and Chornobyl, and hydroelectric power generation cascades, of which six on the Dnipro are the largest.

Ukraine has considerable geothermal resources that are used primarily for heat supply. There is a strong interest in the use of biomass potential. If it is given the good technical potential and experience with existing capacity, renewable energy prospects are reasonably good. In the future, the need for power is expected to grow calling for intensification of the sector development and optimizing of the organization structure and economic mechanisms of functioning in the market environment.

Exercise 4. Read and translate text A.

Text A. Hydropower

Water constantly moves through a vast global cycle, the hydrologic cycle, in which it evaporates from lakes and oceans, form clouds, precipitates as rain or snow, then flows back to the ocean. The energy of this water cycle, which is driven by the sun, is tapped most efficiently with hydropower.

The earth's constant flow of water can be harnessed to produce useful mechanical and electric power.

Prior to the widespread availability of commercial electric power, hydropower was used for irrigation, milling of grain, textile manufacture and the operation of sawmills.

The energy of moving water has been exploited for centuries. In India, water wheels and watermills were built. In Imperial Rome, water powered mills produced flour from grain. In China and the rest of the Far East, hydraulically operated "pot wheel" pumps raised water into irrigation canals. In the 1830s at the peak of the canal-building era, hydropower was used to transport barge traffic up and down steep hills using inclined plane railroads. Direct mechanical power transmission was required, for industries using hydropower had to locate near waterfall. For example, during the last half of the 19-th century, many grist mills were built at SaintAnthonyFalls, utilizing the 50 foot (15 metre) drop in the Mississippi River. The mills contributed to the growth of Minneapolis.

During the industrial Revolution, large water wheels were used to run machinery in factories. The power was not completely reliable, however. Floodwaters created more power than was needed and draughts left the factories without power. By the end of 1800-s, the steam engine had replaced water power in most factories. The first Water powered plant for generating electricity was built in Wisconsin, USA, in 1882. This hydroelectric plant established water power as an important source of electricity. Hydroelectric power is now used all over the world. Almost all water is used to generate electricity. Hydroelectric power now supplies about 19% of world electricity.

Text B

So hydropower is a great source of energy and is used to make electricity. It makes electricity by storing water by using a dam and putting it into a reservoir and forcing the water by a turbine. It all works like this: Water from the reservoir is forced into a pipe called "penstock" which flows and forces a turbine (propeller) which is connected to a "powerhouse generator" with a rod. This gets the generator turning and producing electricity. The electricity flows out through power lines and to wherever it is needed, allowing low cost energy to be used at long distances from the watercourse. Hydroelectric power now supplies 19% of world electricity.

Hydropower is the most important renewable energy source.

It is 97 % renewable and is used for many reasons. It is used to run major factories cheaply and used to get electricity to a handful of homes across the world. About 20% of the world's electricity comes from hydropower. When such fuel as coal, oil and even nuclear fuels are burned up as a source of energy, they cannot be reused. But water used as a source of energy is not used up.

Hydropower is considered one of the most environmentally friendly sources of energy. This is mainly because it does not involve the burning of oils and gases, which pollute the air and cause acid rain which kills trees, plants and small animals. Hydropower is the cheapest and safest source of energy.

It is said that: "Hydroelectricity is the source that can come "on line" quick enough in an energy crisis of the nation." Hydropower in the United States makes enough energy to meet the needs of 28 million residents. Norway's electricity is about 99% hydroelectric; New Zealand's electricity is 75% hydroelectric.

Ukraine's power sector is the twelfth largest in the world in terms of installed capacity. Ukraine generated 177 billion kilowatt hours of electricity. Ukraine has sufficient generating capacity to supply more than twice its electricity needs. In 2006 Ukraine increased electricity exports by almost 25% or over 2 billion KWh.

Text A. Renewable energy

Kinds of renewable energy.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy comes from the natural flow of sunlight, wind, or water around the Earth. With the help of special collectors, we can capture some of this energy and put it to use in our homes and businesses. As long as sunlight, water and wind continue to flow and trees and other plants continue to grow, we have access to a ready of supply of energy. Ukraine has a program of state support for the development of nontraditional and renewable energy sources and small hydro power plants.

Solar energy is energy from the sun in the form of heat and light. This energy drives the climate and weather and supports virtually all life on the Earth. Heat and light from the Sun, along with secondary solar resources as wind and wave power, hydroelectricity and biomass, account for over 99,9% of the available flow of renewable energy on the Earth.

Solar energy technologies harness the sun's heat and light for practical needs suchas heating, lighting and electricity. These technologies date from the time of the early Greeks, Native Americans and Chinese, who warmed their buildings by orienting them towards the sun. Solar energy is becoming increasingly popular for remote power needs such as telecommunication towers, agricultural applications (irrigation and pasture management), in tropical countries that are not connected to an electric grid, for heating swimming pools an many other applications around the world.

Wind energy. Wind energy is really just another form of solar energy. Sunlight falling on oceans and continents causes air to warm and rise, which in turn generates surface winds. Humans have used the wind for thousands of years, first to carry ships across oceans and later to pump water and grind grain. More recently, wind has been harnessed as a clean, safe source of electricity.

Biomass energy. The term 'biomass" refers to any form of plant or animal tissue. In the energy industry, biomass refers to wood, straw, biological waste products such as manure, and other natural materials that contain stored energy. The energy stored in biomass can be released by burning the material directly, or by feeding it to microorganisms that use it to make biogas, a form of natural gas. Energy from biomass is still used around the world, for everything from cooking and heating to generating electricity.

Geothermal power (from the Greek words geo, meaning earth and thermal, meaning heat) is energy generated by heat stored beneath the Earth's surface or the collection of absorbed heat in the atmosphere and oceans. Geothermal steam and hot springs have been used for centuries for bathing and heating, but it wasn't until the 20-th century that geothermal power started being used to make electricity.Geothermal energy is clean and safe for the surrounding environment; the hot water used in the geothermal process can be re-injected into the ground to produce more steam. Geothermal plants work day and night, they are unaffected by changing weather conditions. Geothermal power is generated in over 20 countries around the world.

Exercise 10. Read and translate text B.

Text B. Non-renewable energy

Non-renewable energy sources come out of the ground as liquids, gases and solids. They are considered non-renewable because once they are removed from the ground and used; they are not - immediately replaced. In fact, the world's natural gas, crude oil and coal deposits took millions of years to form. Uranium, which is used for nuclear energy, has limited supply as well. Humans will have used up most of these deposits in less than 200 years. Once they are gone, non- renewable energy supplies cannot be replaced within human time scales. Let’s consider non-renewable energy sources. Coal (fossil fuel) is formed from fossilised plants and consisting of carbon with various organic and some inorganic compounds. Coal is a ready-made fuel. Oil (fossil fuel)is a carbon-based liquid formed from fossilised animals. It can be relatively cheap to mine and to convert into energy Natural gas (fossil fuel) is often used in houses for heating and cooking. Burning of oil, coal and gas give off atmospheric pollutants, including greenhouse gases. Nuclear radioactive minerals such as uranium are obtained by mining. A small amount of radioactive material produces a lot of energy, however, nuclear waste is highly toxic, and needs to be safely stored for 100s or 1000s of years. Accidental leakage of nuclear materials can have a devastating impact on people and the environment. The worst nuclear reactor accident was at Chernobyl, Ukraine in 1986. Some resources can be thought of as both renewable and non-renewable. Wood can be used for fuel and is renewable if trees are replanted as well as biomass, which is material from living things. They are cheap and readily available source of energy, but if they are not replanted, they refer to non-renewable source of energy.

 

Exercise 11. Describe non-renewable energy sources using such professional terms: liquid, gases, solids, crude oil, human time scales, fossilized plants, inorganic components, ready-made fuel, mine, accidental leakage, devastating impact.

Text A. Types of Water Power

There are many types of water power:

Mechanical power, water wheels, used for hundreds of years to power mills and machinery

Hydraulic power, hydroelectric energy, usually referring to hydroelectric dams or run-of-the-river setups

Tidal power, which comes from inside by pants

Tidal steam power, which does the same vertically

Wave power, which uses the energy in waves

Hydropower harnesses the energy of moving or falling water for some useful purposes.

 

Mechanical power.

Prior to the widespread availabilityof commercial electricity, hydropower was widely used for milling, textile manufacture and the operation of sawmills. Wheels mounted on a frame over a river were the first devise used to harness water power. Blades around the wheels dripped into the river, and the flowing water striking the blades caused the wheels to turn. The ancient Romans connected water wheels to grinding stones and used the power to mill grain.

Hydraulic power.

Hydropower is created by capturing energy from moving water. Usually, hydro power works by capturing the potential energy of dammed water, which drives a water turbine and generator as it is piped down a hill at high pressure to produce electricity Today the largest use of hydropower is for electric power generation. Many hydroelectric plants are combined with thermal power plants (those using fuel). With this combination the thermal plant can supply power if the hydroelectric plant is affected by draught. Hydroelectric plant s are especially useful for producing electricity during periods of great demand, because they can be turned on and off rapidly. In Ukraine, thermal power plants (oil, natural gas, coal) account for nearly 50% of generation, with nuclear power generating another 45% and hydroelectric generation accounting for approximately 5%. The country is currently in the process of revamping its electricity sector, through privatization, increased utilization at existing facilities and the completion of two new nuclear plants. The potential water power of the entire world is about 2.25 billion kilowatts of electric power. This is a very general estimate, because the flow of many large rivers has not been measured. Of this enormous potential, only about 600 million kilowatts is developed. The United States has about a sixth of the world's developed power. Canada, Australia and Europe have most of the rest of the developed power. The potential of Asia, Africa, and Latin America is just beginning to be developed.

Tidal power.

Harnessing the tides in a bay or estuary could be achieved with a large tidal range. The tapped water turns turbines as it is released through the tidal barrage in either direction. But possible fault is that the system would generate electricity most efficiently in bursts every six hours (once every tide). This limits the application of tidal energy.

 

Tidal steam power.

A relatively new technology, tidal steam generators draw energy from currents in much the same way that wind generators do. The higher density of water means that a single generator can provide significant power. This technology is at the early stages of development and will require more research before it becomes a significant contributor.

Wave power.

Harnessing power from ocean surface wave motion might yield much more energy than tides. The feasibility of this has been investigated. Generators either coupled to floating devices or turned by air displaced by waves in a hollow concrete structure would produce electricity. Numerous technical problems have frustrated progress. Wave energy is captured by an air driven generator and converted to electricity.

Micro-hydropower Projects produce 100 kilowatts(kW) or less. Microhydro plants can utilize low heads or high heads

 

Pumped storage pumps water from a lower reservoir to an upper reservoir at times when demand for electricity is low. During periods of high electrical demand, the water is released back to the lower reservoir to generate electricity.

Run-off-river project – utilize the flow of water within the natural range of the river, requiring little or no impoundment. Run-off-river plants can be designed using large flow rates with low head or small flow rates with high head

Text A. Why is renewable energy important today?

Energy Price Stability

In the last three years, we have seen large fluctuations in the cost of natural gas, oil, and electricity due to global economics, market deregulation, and political events in some parts of the world. Renewable energy is not subject to sharp price changes because it comes from sources such as sunshine, flowing water, wind, and biological waste, all of which are free. This gives people greater certainty about the cost of energy, which is good for society and the economy. By comparison, fossil fuels are limited in their supply, and their price will increase as they become scarcer.

CleanAir

Air pollution is a major problem in many cities in Canada and around the world. The biggest cause of air pollution in cities is the burning of fossil fuels, including fuels used for transportation. The Canadian federal government estimates that more than 16,000 Canadians die prematurely each year from diseases caused by air pollution. Thousands more suffer from long-term sicknesses and disabilities. The great advantage of using renewable energy in place of fossil fuels is that renewable energy adds very few pollutants to the environment. Renewable energy is considered "clean" and "green."

Protecting Global Climates

When fossil fuels are burned, they release carbon dioxide. This gas acts like an invisible blanket, trapping more of the sun's energy in the atmosphere, causing the Earth to warm up little by little. Carbon dioxide is building up in the atmosphere as more and more fossil fuels are used in homes, factories, and automobiles. If this continues, most scientists think our planet is likely to become significantly warmer, which could cause many serious problems around the world. These problems could include melting of arctic ice, increased forest fires, rising sea levels, loss of animal habitat, damage to coral reefs, the spreading of tropical diseases, expanding deserts, and more frequent and severe storms.

Protecting Landscapes and Watersheds

Some energy projects, particularly big coalmines, hydro dams, and oil and gas activities, can have a large impact on lands and watersheds. Damage or loss of natural lands and watersheds is likely to affect humans and animals. For example, wilderness areas could be lost for when energy resources are extracted. Hydro dams can flood large areas, while the facilities associated with oil and gas and oil sands development can affect forests and disrupt animal movements and migrations. On the other hand, solar energy can provide a continuous supply of energy, which is integrated directly into buildings so that it has very little impact on land use. Run-of-river hydro plants can be designed to allow for free flow of existing streams.

TextB

UnlimitedSupplies. Renewable energy supplies will never run out. While the supplies of coal, oil, and natural gas are limited, sunshine, wind, biomass, and waterpower are considered almost limitless resources. Canada's coal supply is expected to last 200 years, and natural gas about 100 years. Our large, untapped supplies of wind, sun, water, and biomass can power our society indefinitely.

Jobs and Economy. Renewable energy can be developed in such a way that every household or neighbourhood could have its own renewable power generating equipment. This would create many new jobs for people involved in setting up and maintaining this energy supply, and in manufacturing the equipment. It is also more efficient to produce renewable energy in small amounts right where it is needed. The energy losses and equipment needed to transmit power over long distances can also be minimized in this way.

Exercise 3. Read and translate text A.Be ready to prove the statements:

a) Has small-scale hydro or micro-hydro powerbeen increasingly used as an alternative energy source ?

b) Why has it happened so? If you do not agree, give your arguments.

 

Text A. Small-scale hydropower

Small-scale hydro or micro-hydro power has been increasingly used as an alternative energy source, especially in remote areas where other power sources are not viable. Small-scale hydropower system can be installed in small rivers or streams with little or no discernible environmental effect on things such as fish migration. Most small-scale hydropower systems make no use of a dam or major water diversion, but rather use water wheels.

There are some considerations in a micro-hydro system installation. The amount of water flow available on a consistent basis, since lack of rain can affect plant operation. Head is the amount of drop between the intake and the exit. The more head, the more power can be generated. There can be legal and regulatory issues, since, most, countries, cities, and states have regulations about water right and easements.

Over the last few years, the US. Government increased support for alternative power generation. Many resources such as grand, loans, and tax, benefits are available for small-scale hydro systems. In poor areas, many remote communities have no electricity. Micro hydro power, with a capacity of 100 kW or less, allow communities to generate electricity.

Micro- hydropower can be used directly as “shaft power” for many industrial applications. Alternatively, the preferred option for domestic energy supply is to generate electricity with a generator or a reversed electric motor that, while less efficient is likely to be available locally and cheaply.

Unit 5. Text B. Micro hydro, pico hydro

Micro Hydro is a term used for hydroelectric power installations that typically produce up to 100 kW of power. They are often used in water rich areas as a Remote Area Power Supply (RAPS). There are many of these installations around the world, including several delivering around 50 kW in the Solomon Islands, supplying energy for small communities. Micro hydro is frequently accomplished with a Pelton wheel for high head, low flow water supply. The installation is often just a small-dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing. Since the water flows in, then out of it, it cleans itself and is less prone to jam with debris. Micro hydro systems complement photovoltaic solar energy systems because in many areas, water flow, and thus available hydropower, is highest in the winter when solar energy is at a minimum.

Pico hydro is a term used for hydroelectric power generation of under 5 kW. It is useful in small, remote communities that require only a small amount of electricity - for example, to power one or two light bulbs in a house, or a radio, for part of the day. Pico hydropower is more environmentally friendly than burning fossil fuels, as it does not pollute the air. Two examples of pico hydropower can be found in Kenya. These sites produce 1.1 kW and 2.2 kW, respectively. Local residents were trained to maintain the hydro schemes.

Exercise 11. Read and translate text B:

Exercise 3. Read and translate text A.Say: do you agree with the position that hydroelectric projects can be disruptive to surrounding aquatic ecosystems? If yes – give sound reasons; if not – than prove it.

 

Text A. Disadvantages

Environmental damage.

Hydroelectric projects can be disruptive to surrounding aquatic ecosystems both upstream and downstream of the plant site. Studies have shown that dams have reduced salmon populations by preventing access to spawning grounds upstream, even though most dams in salmon habitat have fish ladders installed. Salmon spawn is also harmed on their migration to sea when they must pass through turbines. So turbine and power plant designers are required new research projects or a condition of relicensing of existing projects. Generation of hydroelectric power changes the downstream river environment. Water exiting a turbine usually contains very little suspended sediment, which can lead to scouring of riverbeds and loss of riverbanks. Since turbine gates are often opened intermittently, rapid or even daily fluctuations in river flow are observed. Dissolved oxygen content of the water may change from pre-construction conditions. Depending on the location, water exiting form turbines is typically much warmer than the pre-dam water, which can change aquatic faunal populations, including endangered species and prevent natural freezing processes from occurring. In some cases, the entire river may be diverted leaving a dry riverbed. Since damming and redirecting the waters for agricultural and energy use, many native and migratory birds have become increasingly endangered.

Greenhouse gas emissions. The reservoirs of power plants in tropical regions may produce substantial amounts of methane and carbon dioxide. This is due to plant material in flooded areas decaying in an anaerobic environment and forming methane, a very potential greenhouse gas.

Population relocation. Another disadvantage of hydroelectric dams is the need to relocate the people living where the reservoirs are planned. Historically and culturally important sites can be flooded and lost.

Dam failures. Failures of large dams, while rare, are potentiallyserious.Dams may be subject to enemy bombardment during wartime, sabotage and terrorism. The creation of a dam in a geologically inappropriate location may cause disasters like in 1963 in Italy where almost 2000 people died.

Exercise 10. Read and translate text B.

 

Text B. Advantages of electricity generation

Economics. The major advantage of electricity is elimination of the cost of fuel. The cost of operating a hydroelectric plant is nearly immune to increases in the cost of fossil fuels such as oil, natural gas or coal. Fuel is not required and so it need not be imported. Hydroelectric plants tend to have longer economic lives than fuel-fired generation, with some plants now is service having been built 50 years ago. Operating labor cost is usually low since plants are automated and have few personnel on site during normal operation. A hydroelectric plant may be considered with relatively low construction cost. It has been calculated that the sale of electricity from the Three Gorges Dam will cover the construction costs after 5 to 8 years of full generation.

Greenhouse gas emission. Since hydroelectric dams do not burn fossil fuels, they do not directly produce carbon dioxide (a greenhouse gas).

Related activities. Reservoirs created by hydroelectric schemes often provide facilities for water sports and become tourist attractions in themselves. In some countries farming fish in the reservoirs is common. Large hydro dams can control floods. Boats may be used to improve transportation, when dams create reservoirs and eliminate rapids.

Hydroelectricity avoids the hazards of coal mining and the direct health effects of coal emissions.

Hydroelectricity generates no nuclear waste, has none of the dangers associated with uranium mining, nor nuclear leaks.
