Between 1990 and 2010, the number of people with access to electricity increased by 1.7 billion. That’s progress to be proud of. And yet, as the world’s population continues to rise, still more people will need cheap energy to light their homes and streets, use phones and computers and do their everyday business. The way we get that energy is at issue; fossil fuels and greenhouse gas emissions are making drastic changes in the climate, leading to big problems on every continent. Instead, we can become more energy-efficient and invest in clean energy sources such as solar and wind. That way we’ll meet electricity needs and protect the environment. How’s that for a balancing act?
