Here’s the good news: wind power, solar power, and other renewable forms of energy are expanding far more quickly than anyone expected, ensuring that these systems will provide an ever-increasing share of our future energy supply. According to the most recent projections from the Energy Information Administration (EIA) of the U.S. Department of Energy, global consumption of wind, solar, hydropower, and other renewables will double between now and 2040, jumping from 64 to 131 quadrillion British thermal units (BTUs).
And here’s the bad news: the consumption of oil, coal, and natural gas is also growing, making it likely that, whatever the advances of renewable energy, fossil fuels will continue to dominate the global landscape for decades to come, accelerating the pace of global warming and ensuring the intensification of climate-change catastrophes.
The rapid growth of renewable energy has given us much to cheer about. Not so long ago, energy analysts were reporting that wind and solar systems were too costly to compete with oil, coal, and natural gas in the global marketplace. Renewables would, it was then assumed, require pricey subsidies that might not always be available. That was then and this is now. Today, remarkably enough, wind and solar are already competitive with fossil fuels for many uses and in many markets.
