today’s climate of growing energy needs‚ it is imperative to find sources of renewable or limitless energy. There is a plentiful amount of fossil fuels‚ including coal‚ natural gas‚ and oil. It remains to been seen however‚ if these resources can be depended on in the future. According to the United States Energy Information Administration‚ the U.S. “is the birthplace to some of the word’s greatest clean energy technology”‚ but produces less than half of Germany’s clean energy program. In the last

Energy crisis is a major challenge that should be overcome in modern times when people have embraced the use of electric devices in performing various activities. Consequently‚ the use of these electric devices leads to heavy consumption of electric power that calls for the adoption of energy efficient appliances. Energy efficiency refers to reduced use of energy in a given service (Dorsi & Krigger‚ 2008). The reduced consumption of energy is as a result of technological advancement as well as from

Energy Efficient Building Windows Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers. A smaller airspace doesn’t insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window

Energy Production Controversy Imagine the U.S. without cars‚ motorcycles‚ planes‚ or boats. The daily lives of U.S. citizens would be completely different. The common denominator for all those modes of transportation is that they run on gas‚ which is made from fossil fuels. Fossil fuels such as oil‚ coal‚ and natural gas are nonrenewable resources. They will run out one day and that’s what the U.S. relies on for gas and electricity. Renewable energy such as solar‚ wind‚ and hydropower are infinite
