This post is by Chris Goodall, author of The Switch, which describes how the world can cost effectively move to a zero carbon economy.
Sometimes we just don’t notice how well things are going in the race to decarbonise the world economy. Solar photovoltaic panels (PV) continue to decline sharply in cost. Batteries are becoming rapidly cheaper and we will have inexpensive electric cars with 200 miles of range within eighteen months. Wind turbines are improving in price and performance, particularly offshore. Energy use is proving easy to manage second by second. Optimism about a prosperous low carbon future for all seven billion people in the world is more justified with each passing month.
