Attempts to fight climate change by reducing the demand for energy haven’t worked. Fortunately, scientists, engineers, and entrepreneurs have been working hard on the supply side to make clean energy convenient and cost-effective.
Due to steady technological and manufacturing advances, the price of solar cells has dropped 99.5% since 1977. Solar will soon be more cost efficient than fossil fuels. The cost of wind energy has also dropped to an all-time low, and in the last decade represented about a third of newly installed US energy capacity.
Forward thinking organizations are taking advantage of this. For example, in India there is an initiative to convert airports to self-sustaining clean energy.
Tesla is making high-performance, affordable electric cars, and installing electric charging stations worldwide.
There are hopeful signs that clean energy could soon be reaching a tipping point. For example, in Japan, there are now more electric charging stations than gas stations.
And Germany produces so much renewable energy, it sometimes produces even more than it can use.
