100% Renewable Energy: What We Can Do in 10 Years
But the transition will entail costs—not just money and regulation, but also changes in our behavior and expectations. It will probably take at least three or four decades, and will fundamentally change the way we live.
Nobody knows how to accomplish the transition in detail, because this has never been done before. Most previous energy transitions were driven by opportunity, not policy. And they were usually additive, with new energy resources piling onto old ones (we still use firewood, even though we’ve added coal, hydro, oil, natural gas, and nuclear to the mix).
Since the renewable energy revolution will require trading our currently dominant energy sources (fossil fuels) for alternative ones (mostly wind, solar, hydro, geothermal, and biomass) that have different characteristics, there are likely to be some hefty challenges along the way.
Therefore, it makes sense to start with the low-hanging fruit and with a plan in place, then revise our plan frequently as we gain practical experience. Several organizations have already formulated plans for transitioning to 100 percent renewable energy.
