Hydroelectric power (hydropower) is a largely untapped source of energy that you can harness without producing harmful emissions. The Earth's atmosphere acts like an engine, doing all the work to...
Green energy is created from natural resources that do not cause harmful pollution to Earth's surface or atmosphere. With the concern of global warming and depleting natural resources,...
There's a huge push to do things that are environmentally-friendly. Some of the ideas have been around for decades while others, like green electricity, are relatively new to consumers. Buying...
Providing a substantial portion of the electricity generated worldwide, and with potential for more in the future, hydropower is a major component of meeting the globe's electrical demands....
Over the past fifteen years, a significant amount of research and attention has been focused on exploring and expanding sources of renewable energy. Unlike fossil fuels, such as petroleum that...
Alternative energy is any form of energy derived from means that do not include fossil fuels or nuclear power. Climate change is the primary motivator in the design of the different forms of...
The 2007 to 2008 spike in fossil fuel prices combined with the widespread acceptance of Global Warming as a phenomenon to renew interest in green, alternative energy in a way never before seen....
The general acceptance of global warming and the 2007-08 surge in fossil fuel prices have come together to attract interest to green, alternative energy in a way never before seen. Today,...
Wind, as a natural element, is considered a form of solar energy. The earth's continuous rotation, and its uneven terrain coupled with varying conditions of heat throughout the atmosphere cause...
Hydropower, otherwise known as hydroelectric power, uses water to generate electricity. When water is at a high point, such as the mouth of a river, it has potential energy. As the water flows...
Coal continues to be a major source of energy in the United States. Coal power supplied about 49 percent of the nation's electricity in 2007, according to the Energy Information Administration....
From river-driven mill wheels to massive hydroelectric dams, humans have long harnessed water and other liquids as an energy source. Hydraulic power is a powerful alternative energy source, and...
With the supply of oil and gas diminishing, many people are turning to renewable energy as a viable source of electricity. There are many types of renewable energy sources, including wind, solar...
We have relied on fossil fuels for our energy needs because, historically, these fuels have been relatively inexpensive, and profitable for developers. With rising fuel prices, concerns about...
Conventional sources of energy include oil, natural gas, nuclear power, coal and hydropower. All of these except for hydropower are non-renewable resources, meaning their supply is limited.
Alternative energy sources are becoming more valuable as fossil fuels become more difficult to find and more expensive to extract. Scientists theorize that fossil fuels are causing climate change...
As the Earth's climate changes, fuel policy is beginning to follow suit. The business sector's desire for a renewable source of fuel has brought a growth in new technology and the discovery of...
China remains a major producer and distributor of resources. It is in fact, a world leader in the production and manufacturing of many coveted natural resources. The geography of such a large area...
California is an abundant source of natural resources. A vast state, its many climates offer a variety of sources of food, energy and shelter which make California a friendly climate in which to...
Alternative energy has received more attention in the national and international media as the pollution from fossil fuels becomes more apparent. Global warming and declining air quality are two...
Water is a finite resource on Earth. The rain cycle--powered by the energy of the sun--distributes water to the different areas of the planet. You might have experienced a drought near you and...
For years, people have been using conventional sources of energy, primarily fossil fuels. However, recent concerns about climate change and energy independence have sparked a uptick in interest...
Today, American uses more than a quarter of the world's energy. From solar power, which will be available as long as the Sun shines on the Earth, to fossil fuels, which we get closer to burning...
Water plays an array of vital roles in ecosystems across the planet. Although many other substances are necessary for life and for ecosystems to exist, without water nothing else would function to...
Non-conventional energy sources are being researched to reduce our dependence on fossil fuels that pollute the environment and leave the United States dependent on foreign countries for resources....
Fossil fuels like coal, oil and gas have long been the primary resource for energy. However, these are non-renewable resources, meaning that there is not an unlimited supply. In addition, these...
With the rise in concern about the environment in general since the 1960s, and the growing concerns about global warming over the past 20 years, governments, businesses and individuals all look...
