Turn Your House Into A “Green” Energy Machine
Renewable energy is energy that is replenished by nature itself. Unlike fossil fuels, renewable power sources will never be exhausted. This form of energy is also known as “green energy” because it can usually be harnessed without creating lasting harm to the planet. Rather, people can use it in a way that is completely in harmony with nature. Green energy normally produces little pollution, so even larger energy-producing operations can have limited environmental impact. For all these reasons, green power is also called “alternative energy” — an alternative to fossil fuels. Some examples of green power include wind, solar, and geothermal.
One of the reasons people might integrate renewable energy into their homes is to reduce their carbon footprint. The carbon footprint is a measure of how much carbon dioxide a household contributes to the atmosphere. Scientists who study climate have come to a consensus that the rising concentration of carbon dioxide and other “greenhouse gases” in the atmosphere is associated with higher average temperatures on Earth. These gases work to trap solar radiation within the atmosphere, thus influencing how much heat from the sun becomes locked up in Earth’s vicinity and affects the planet’s surface.
