Introduction
Renewable energy as defined in the glossary of “Renewable Energy; Myths and Obstacles” is a source of energy that regenerates over a period of time. However, this period of time is significantly shorter than the time it takes for nonrenewable energy sources to regenerate. The most common nonrenewable energy source is fossil fuel. Usually renewable energy depends on the sun’s energy to regenerate; solar energy, wind power and hydropower are examples of renewable energy sources that depend on the sun.

Renewable energy, also known as clean energy, is becoming a fast growing phenomenon. President of the United States of America, Barack Obama, mentioned in a recent speech that USA spends nearly one billion dollars a day on purchasing oil from other countries. He also stressed on the fact that air pollution caused by those fossil fuels is becoming one of the biggest worldwide problems. On June 15 in the year 2010, he said, “Now, there are costs associated with this transition. And some believe we can’t afford those costs right now. I say we can’t afford not to change how we produce and use energy— because the long-term costs to our economy, our national security, and our environment are far greater.”

Renewable energy is the solution for high-energy demands because it is eco-friendly, economical and inexhaustible amongst many other reasons. However, some might argue that it is not reliable and is inefficient.

Ecofriendly

Renewable energy is considered environment friendly because it does not give off emissions. It works with elements from the weather, which is available and changing everyday. Some examples are solar, wind and geothermal resources. As shown in a study conducted by the US Environmental Protection Agency, EPA, the emissions released from those sources are negligible because no combustion of fossil fuels occurs; therefore no carbon
