Text 7. Non-traditional sources of energy
Wind energy and bioenergy are considered to be non-traditional sources of energy. We have been harnessing the wind's energy for hundreds of years from old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent – a wind turbine – can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air is formed on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity. Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. Stand-alone wind turbines are typically used for water pumping or communications. However, homeowners or farmers in windy areas can also use wind turbines as a way to cut their electric bills. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant. Several electricity providers today use wind plants to supply power to their customers. We have used bioenergy – the energy from biomass (organic matter) – for thousands of years, ever since people started burning wood to cook food or to keep warm. And today, wood is still our largest biomass resource for bioenergy. But many other sources of biomass can now be used for bioenergy, including plants, residues from agriculture or forestry, and the organic component of municipal and industrial wastes.
The use of bioenergy has the potential to reduce our greenhouse gas emissions. Bioenergy generates about the same amount of carbon dioxide as fossil fuels, but every time a new plant grows, carbon dioxide is actually removed from the atmosphere. The net emission of carbon dioxide will be zero as long as plants continue to be replenished for bioenergy purposes. The energy crops, such as fast-growing trees and grasses, are called bioenergy feedstocks. The use of bio energy feedstocks can also help increase profits for the agricultural industry.
Text 8. Energy of seas and oceans
The ocean can produce two types of energy: thermal energy from the sun's heat, and mechanical energy from the tides and waves. Oceans cover more than 70 % of Earth's surface, making them the world's largest solar collectors. The sun's heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world. Ocean thermal energy is used for many applications. Ocean mechanical energy is quite different from ocean thermal energy. Even though the sun affects all ocean activity, tides are driven primarily by the gravitational pull of the moon, and waves are driven primarily by the winds. As a result, tides and waves are intermittent sources of energy, while ocean thermal energy is fairly constant. Also, unlike thermal energy, the electricity conversion of both tidal and wave energy usually involves mechanical devices. A barrage (dam) is typically used to convert tidal energy into electricity by forcing the water through turbines, activating a generator. For wave energy conversion, there are three basic systems: channel systems that turn the waves into reservoirs; float systems that drive hydraulic pumps; and oscillating water column systems that use the waves to compress air within a container. The mechanical power created from these systems either directly activates a generator or transfers to a working fluid, water, or air, which then drives a turbine/generator.
The tide moves a huge amount of water twice each day, and harnessing it can provide a great deal of energy. Although the energy supply is reliable and plentiful, converting it into useful electrical power is not easy. Only about 20 sites in the world have been identified as possible tidal power stations.
Tidal power stations work just as hydro-electric stations, but the dam is much bigger. A huge dam (called a "barrage") is built across a river estuary. When the tide goes in and out, the water flows through tunnels in the dam. The ebb and flow of the tides can be used to turn a turbine, or it can be used to push air through a pipe, which then turns a turbine. Large lock gates, like the ones used on canals, allow ships to pass.
The largest tidal power station in the world (and the only one in Europe) is in the Ranee estuary in northern France, near St. Malo. It was built in 1966. A major drawback of tidal power stations is that they can only generate when the tide is flowing in or out.
The Kola Peninsula possesses tidal energy, which can be used as non-traditional energy too. Many years of research have given experts a deep insight into the issue of application of this type of energy. A 400-kilowatt experimental tidal power plant has been built in Kislaya Bay, on the coast of the Barents Sea. Cross sections have been evaluated for the construction of larger tidal power plants in Dolgaya Bay near the village of Teriberka and in the Lumbovsky Gulf of the White Sea.
