The higher the amount of our energy use is renewable, the less we’ll rely on imported energy, and the more we’ll contribute to U.S. energy independence. Renewable energy sources can help us minimize the geo-political risks associated with fossil fuels, from trade disputes to political instability to pricing wars, which are often rooted in .

Fossil fuels also cause air pollution and can contaminate water and soil. Energy from renewable resources prevents air pollution, which makes the air safer to breathe, leading to better health and lower health care bills. Valley Children''s Healthcare breaking ground on a DOE funded renewable energy microgrid expected to provide 80% of the
Energy lies at the core of the climate challenge — and holds the key to its solution. Most greenhouse gasses responsible for causing global warming are produced by burning fossil fuels for electricity and heat..

Causes and Consequences: Renewables Provide Little of Our Energy Despite the appeal of renewable energy sources, they currently comprise less than 14% of our global energy supply and generate less than 19% of our electricity. Moreover, the "new renewables" account for only a very small fraction of these numbers.
Moreover, the "new renewables" account for only a very small fraction of these numbers. The fact that renewables provide little of our energy is a dilemma with multiple causes and consequences. However, most renewable sources are now expanding quickly, and there are many ways in which we can encourage their development and spread.
o Used for electricity, heating, cooking (burning biomass directly), & transportation fuel (ex. Ethanol-grow corn) o Wood & charcoal; animal products & manure o Pro: sustainable if done right o Con: massive pollution and habitat destruction if done wrong
Overall, clean energy is considered better for the environment than traditional fossil-fuel–based resources, generally resulting in less air and water pollution than combustible fuels, such as coal, natural gas, and petroleum oil. Power generated by renewable sources, such as wind, water, and sunlight, does not produce harmful carbon dioxide emissions that lead to climate change,
By 2017 that had fallen to 300.5 million Btu, the lowest level in five decades. In 2018, though, per capita energy use rose to 309.3 million Btu. (Per capita energy use peaked in 1979 at 359 million Btu.) Looked at a different way, the U.S. economy has become steadily less energy-intensive since the end of World War II.
Moreover, the "new renewables" account for only a very small fraction of these numbers. The fact that renewables provide little of our energy is a dilemma with multiple causes and consequences. However, most renewable sources are now expanding quickly, and there are many ways in which we can encourage their development and spread.
Renewable energy has many benefits, but it''s not always sunny when it comes to renewable energy. Here are some cons of renewable energy when compared to traditional fuel sources: Renewable energy has high upfront costs. Renewable energy is intermittent. Renewables have storage capabilities. Renewable energy sources have geographic limitations.

I chose "Renewables Provide Little of Our Energy" because I believe most people intend to want solar panels for more renewable energy and less footprint on the earth, but we are stopped at solar panels costing between $16,000 and $35,000. Solar panels can reduce energy bills, as it generates all the electricity from the sun. There are also tax credits you can
