Getting to 100% renewable: dream or reality?

​Attending the Future of Energy Summit last month, an annual event hosted by Bloomberg New Energy Finance, I was struck – for the second year running – by the rapid pace of cost reductions and innovation happening across the clean energy spectrum. With the news that a recent solar photovoltaics tender in Dubai obtained bids at less than US6c/kWh, to major investments in electricity storage and electric vehicles, to increased interest in demand-side management at the grid and consumer level, the message is clear: clean energy has most likely reached a crucial tipping point that will start to suck in increasing levels of investment. Some commentators also noted the opportune timing: with capital investment in upstream oil production sharply curtailed due to falling global prices, there is potentially a lot of financial capital looking for a home.
 
But perhaps one of the more interesting messages was the one coming from progressive regulators here in the U.S. The head of the California Public Utilities Commission, Michael Picker, noted that with renewable energy already supplying 40% of the state’s electricity a few days last year, the target for 50% renewables by 2030 is “not really a challenge”. Perhaps more interesting, he seemed very relaxed on reaching 100% renewables at some point in the future, on the back of strategic generation placement, transfers to neighboring states, and embedded storage. And note that we’re not talking about large hydropower here, which supplies between 6-12% of California’s electricity and is unlikely to increase.

Whether it be from The Wall Street Journal, or YouTube, by now most of us have heard the arguments for and against development of “shale gas”, and as a member of the World Bank’s Oil, Gas and Mining Unit, hardly a day goes by that I do not receive a notice about an article, a presentation or a conference on this topic.

Solar lights aimed at African market work overtime around Washington Beltway

When I heard that Jim Yong Kim, the World Bank’s new president, was to meet staff in the energy department where I work on his first day at work July 2, it occurred to me that a good way to introduce him to our work in sustainable energy would be a quick demo of solar lanterns.

I suggested it to my colleague Katherine Steel, the manager of Lighting Africa, a joint Bank-IFC program that has created markets for off-grid solar lights in Africa.
