The past couple of centuries saw industry developed at a rapid pace especially following the Industrial Revolution when manual labor was rendered nearly useless when replaced with machines. In order for machines to operate at peak capacity, intense energy use was required. Little has changed over these two centuries in terms of high energy consumption, which has two negative implications. While the most abundant and extractable energy sources, oil, gas, and coal are exhaustible, which means they will run dry at some point in the future, especially seeing as how world population surplus is palpable these days. More importantly ...

United Kingdom adopted the market for energy approach in 1982 under the stewardship of Mr. Nigel Lawson the then secretary of state in charge of energy. From that time, the power was to be a traded product, just like other commodities and it supply was to be settled in the marketplace. The adoption of that idea was slow and by the early 1990s, most of the energy parastatals had been privatised. Electricity, coal, gas and the nuclear power were all privatised. The old mechanisms and commands like Central Electricity Generating Board were replaced by many companies for generating and ...

Today, solar energy takes up two- tenths of 1% of total energy consumption in the United States in which its electrical capacity has been continually increasing from 334,244 kilowatts in 1997 to 1,488,500 kilowatts in 2011. Expanding solar energy has been faced with several challenges such as variations on availability of sources of sunlight because of changing weather conditions. Due to its intermittent source it needs a back-up energy system when sunlight is not available making it unreliable. Another issue is that the high costs of installation have been causing disadvantages compared to other renewable resources. ...

Sun plays crucial role in the life of the Earth. The entire organic world of our planet is obliged to the Sun for its existence. It is not only the source of light and heat, but also the original source of many other types of energy (oil, coal, water, wind). Since people appeared on the Earth, they began using the sun's energy. According to archaeological data, it is known that housing preference was given to quiet places, closed from the cold winds and open to the sun's rays. Perhaps the earliest known solar system can be considered the statue ...
