Meeting global carbon reduction goals will not be easy, but the good news is that this heavy lift is getting a little lighter each day. In some places, renewable energy technologies are now delivering the cheapest electrons on the planet. Soon, they will no longer be ‘alternative’ technologies at all. As their costs continue to fall, utilities and grid planners are beginning to appreciate that renewables are indeed cost-effective and increasingly becoming mainstream technologies. The emerging challenge will soon be how to wrap other technologies around these emissions-free assets that deliver super-cheap, but intermittent, electrons into our grid.
