Thanks to robust research, new green energy technologies are everywhere, lessoning our dependence on fossil fuels. But what is it & why is it any better than coal or oil?
n the past three decades, research & development in green energy has exploded, yielding hundreds of promising new technologies that can reduce our dependence on coal, oil, & natural gas. But what is green energy, & what makes it a better option than fossil fuels?Green energy defined
Green energy comes from natural sources such as sunlight, wind, rain, tides, plants, algae & geothermal heat. These energy resources are renewable, meaning they're naturally replenished. In contrast, fossil fuels are a finite resource that take millions of years to develop & will continue to diminish with use.
Renewable energy sources also have a much smaller impact on the environment than fossil fuels, which produce pollutants such as greenhouse gases as a by-product, contributing to climate change. Gaining access to fossil fuels typically requires either mining or drilling deep into the earth, often in ecologically sensitive locations.
