Progress in wave and tidal energy hasn’t been slow – it’s been nonexistent.Despite media attention, strategic investments from large energy companies and strong support from national governments, the marine renewables industry has seen mostly technical failure over the last decade.According to Bloomberg New Energy Finance, fewer than 150 megawatts of wave and tidal projects will be installed globally by the end of the decade -- a 72 percent reduction in earlier projections.Aside from creating dams, no companies have yet been able to competitively and reliably tap the waves or tides for electricity.So is it time to end support for marine renewables and spend money on more promising up-and-coming technologies?In this week’s show, we’ll look why companies operating in the space have struggled and ask whether it’s finally time to shift our attention.Then, we’ll discuss the increasingly important role of electric vehicles at the Detroit Auto Show. We’ll also talk about “One Knob,” an idea for creating a more free-market approach to residential energy efficiency.The Energy Gang is produced by Greentechmedia.com. The show features weekly discussion between energy futurist Jigar Shah, energy policy expert Katherine Hamilton and Greentech Media Editor Stephen Lacey.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
