Most of the energy we use today comes from fossil fuels. The lights in our homes, the cars in our garages, and the furnaces in our basements run on oil and gas. Burning fossil fuels releases pollution into the air that harms our health, contributing to asthma, heart attack, premature birth, and a host of other health problems.
Of course, fossil fuels are also warming our climate, with devastating consequences for us and for future generations. If global warming pollution continues at high levels, kids born today could see our oceans rise by up to 10 feet off the coast of Massachusetts within their lifetimes and experience 33 days each summer with temperatures above 100 degrees.
The good news is that it doesn’t have to be that way. Renewable energy is becoming more efficient, affordable, and widespread each year. Instead of burning oil and gas, we can harness pollution-free power from the sun and the wind. We can also cut the amount of energy we use in half by 2050, which will make it easier to repower our lives with clean energy. When our communities run on renewable energy, our air will be cleaner, our families will be healthier, and we’ll have a shot at preventing the worst impacts of global warming.
