Insight and inspiration in turbulent times.
Many outlooks for a mostly renewable U.S. power grid include a lot more high-voltage transmission lines. But is this a realistic hope, considering how few of these lines we’ve built in recent years, and the many barriers they always seem to face?
How to collect that solar energy, predict it, get it to the right places at the right time, save it up for a rainy day — those are the kind of challenges our massive, spread-out, and unevenly populated country faces as we make the switch to clean energy. And it all comes down to a lesson that the Evslins learned the hard way: It’s not about getting off the grid. It’s about building a better one.
Sometimes the most heated debates are among people who almost agree. That seems to be the case with the recent Jacobson-Clack controversy, in which two groups of well-intentioned, renewable energy advocates bitterly spar over differing paths to a 100% renewable energy future. But as PCI Senior Fellow Richard Heinberg points out in his latest essay, neither side is considering one of the most crucial aspects to successfully reaching that future.
Tim Flannery drops into the studio and we discuss why, and talk about his new book (his second follow up to the highly influential The Weather Makers): Sunlight and Seaweed: An Argument For How To Feed, Power, and Clean Up The World.
But what does the transition mean for residents of Essen and the rest of the Ruhr region — the former industrial coal belt — whose lives and livelihoods have been dramatically altered by the reduced demand for coal? The answer to that could hold some useful lessons for those undergoing similar transitions elsewhere.
British Petroleum (BP) publishes its Statistical Review of World Energy, venting out a few catchy phrases that the mainstream media mindlessly repeats. This time the catch-phrase was: “overall energy consumption is growing faster than renewable energies put together”. This discourse is naturally convenient to those set on promoting fossil fuels and/or detracting renewable energy. But is BP really a trustworthy source on the matter?
It seems clear to me now what SolarAid should do in the next year. We should try to work with enough of those companies and organisations, in clever enough ways, that we play a useful role – maybe a catalytic role, if we can – in ensuring that civilisation passes The Test.
On Saturday, we reported that a leaked draft of Energy Secretary Rick Perry’s grid study obtained by Bloomberg debunks his attack on renewable energy. ThinkProgress has now obtained a copy of that draft, and it has many more surprises — or, rather, findings that are fairly well known to energy experts but may come as an unpleasant surprise to Perry and the White House.
Could a combination of wind, solar, and hydroelectricity fully power the U.S. ?
Is it really feasible to run the world on 100% renewables, including supply and demand matching at all times and places? Would doing so require vast amounts of seasonal storage? Are exotic new technologies like next-generation flexible nuclear power plants or coal plants equipped with carbon capture and storage (CCS) equipment needed to balance out variable renewables at a reasonable cost?
In a sharing vision of a local renewable energy system, many households will generate their own renewable energy (as in solar photovoltaic or solar thermal systems on their rooftops), but many more, for whom this is not an option, will share in the ownership and operation of off-site renewable energy generation infrastructure such as wind turbines.
The staggering drop in the cost of clean energy has already upended the global power market over the past two decades — and that trend will only continue for the next two decades, according to new analysis from Bloomberg New Energy Finance (BNEF).
