How much do you know about renewable and sustainable energy? Here's a brief look at some of the top options.
Solar: Whether rooftop panels are placed on your home or business or installed at a community site or solar farm, solar power is one of the most used, most cost-efficient sources of green, renewable power. When the sun shines down from above, solar cells contained within panels capture and transform rays of sunlight into clean electricity that is sentout to the power grid.
Wind: Like the name suggests, wind energy comes from using just that: the wind. As the sun heats up the Earth, hot air rises while cool air fills the space. This movement of air creates wind that, with the help of wind turbines, is captured and becomes a no-carbon-emission energy source.
Biopower: Biopower uses direct combustion to turn organic waste material from wood, crops, manure and some garbage into clean energy. While making a resource out of waste, biopower can also positively impact the environment and agricultural economies.
Hydroelectric: Water contained in lakes held by a dam has incredible potential for creating clean energy. As water spins turbines, the turbines rotate a generator that produces electricity. Even better, hydroelectric energy doesn’t consume any water, which actively supports water’s constantly regenerating natural cycle. Plus, no greenhouse gases are produced.
Landfill Gas: As garbage and waste decompose in a landfill, gas is released. Much of this gas contains methane and carbon dioxide – both potent greenhouse gases. Instead of allowing the gas to escape into the air, the gas emissions are collected, treated and converted into electricity for customers. Used as renewable energy, landfill gas can minimize waste and help reduce emissions that contribute to climate change.
Batteries: Batteries can store electricity generated from solar panels or wind turbines. They also strengthen the power grid by providing backup power for remote areas and controlling the flow of electricity in power lines. Batteries react almost instantly to changes in sun and wind production, and smooth the swings to stabilize the flow of electricity.
