power. Several factors such as the catastrophes in Chernobyl and Fukushima and the depleting of coal and gas reserves have led to the idea behind the renewable power sources. The renewable power sources are the future of the energy production in the world. Renewable energy is the energy that comes from natural resources such as sunlight‚ wind and hydro sources. Those sources are naturally replenished and harmless for the environment. Around 19% of world’s electricity generation comes from renewables

Except for the fact that there were no power lines to our house‚ we looked and lived like just about everyone else in the modern world. But our neighbors thought we were peculiar. "Back to nature" is what they called us. This stereotype didn’t convey everything about our decision to go solar‚ but it made them feel better to put us into a category they understood. We were known

The invention on renewable energy has not only provided an alternative energy resource but has also come with great environmental and socio-economic impacts. Global warming‚ caused by emissions from fossil fuels‚ has become a major threat to the world today. In order to counter this challenge and the other problems associated with fossil fuels‚ there is need to embrace the use of renewable energy sources. However‚ not all technologies that are employed in renewable energy production are appropriate

sun’s contribution to human energy needs is substantial — worldwide‚ solar electricity generation is a growing‚ multibillion dollar industry. But solar’s share of the total energy market remains rather small‚ well below 1 percent of total energy consumption‚ compared with roughly 85 percent from oil‚ natural gas‚ and coal. Those fossil fuels cannot remain the dominant sources of energy forever. Whatever the precise timetable for their depletion‚ oil and gas supplies will not keep up with growing energy
