20.01.2008· Source(s): My father was a professional electrical engineer, project manager, responsible for the design and construction of the grid in the UK (a national network of generators, sub generators, pylons and the cables to supply the electricity. He also designed part of the switchboard for the generator in Kariba Dam, Zimbabwe, and later had a chance to inspect the generators there first hand

Natural gas is extracted by drilling into the ground and using water to move the gas to the surface. After the gas rises to the top, it is necessary to separate it from other substances. Natural gas extraction involves using hydraulic pressure to make gas rise from deep wells to the surface. This begins with drilling a hole deep into the ground

Energy conversion - Energy conversion - Windmills: Windmills, like waterwheels, were among the original prime movers that replaced animal muscle as a source of power. They were used for centuries in various parts of the world, converting the energy of the wind into mechanical energy for grinding grain, pumping water, and draining lowland areas.

How is oil extracted from the ground ? Energy issues have always been important in international relations, but in recent years may have become even more important than in the past due to the widespread awareness of existing limits to energy sources and negative climate impacts. The course discusses global trends in energy consumption and production, various available scenarios for

Windmills vs. Wind Turbines. Sometimes people use the terms "windmill" and "wind turbine" interchangeably, but there are important differences. People have been using windmills for centuries to grind grain, pump water, and do other work. Windmills generate mechanical energy, but they do not generate electricity. In contrast, modern wind

Solar Power is extracted by turning the sun's rays into useful energy that can be used to power homes and businesses. Solar Power is processed and refined by the PV panels use the photovoltaic effect to convert the energy from the sun into electricity, which can then be used to replace a buildings usual supply of electricity.

The sun's nuclear energy turns into radiant energy. When the radiant energy hits Earth, it turns into thermal energy, which makes areas of uneven heating on Earth, which creates areas of different pressure. Because of different pressure, some masses of air would rise and others would sink, and then the air molecules move horizantaly to fill in the empty space. This is wind energy.

Read moreHumans have harnessed energy from the wind for centuries. We've all seen the picturesque windmills gently turning in colorful tulip fields in Holland. Windmills have historically been used to pump water or grind grain and are still used for those purposes. But the more modern windmills that use a wind turbine are able to generate electricity.

FACT SHEET - WINDMILLS MEANINGS: Windmills use the energy of the wind. A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called "sails". Originally windmills were used for milling (grinding) grain into flour for food production. Then its uses expanded to pumping water either to drain water from the land or to extract water from under the

Energy, Ch. 21, extension 2 How a windmill works 5 Windmills cannot extract all the power in the wind, because air must be able to move away from behind the blade and because conversion of mechanical energy involves losses. The maximum fraction of wind power extractable is only 16 27 ≈ 0.6.(37,38) This is known as the Betz limit. The limitation arises because, if the blades slow the wind

Renewable energy is energy derived from natural processes that are replenished at a rate that is equal to or faster than the rate at which they are consumed. There are various forms of renewable energy, deriving directly or indirectly from the sun, or from heat generated deep within the earth. They include energy generated from solar, wind, geothermal, hydropower and ocean resources, solid

Windmills are not a new source of energy : they have been used to produce mechanical power or to pump water since several centuries ago, and they are now being developed to generate electricity, but not in very significant amounts, as can be seen below. The most efficient windmills are not more than 50% efficient in the most even in the most windy places of the world. The power produced by a

Petroleum companies extract crude oil from the Earth using a perforation in the Earth's surface called an oil well. Crude oil is a liquid form of petroleum. In addition, wells provide natural gas. Refining crude oil produces gasoline, diesel fuel and other useful petroleum products. Oil wells are 5 to 36 inches in diameter. The drill bit breaks through the ground and drilling fluid brings the
