Insight and inspiration in turbulent times.
The total solar eclipse that captivated the United States this week was more than just a celestial spectacle (and a reminder to take care of your eyes). It was also a valuable lesson in how to manage electricity grids when a crucial generation source – solar power, in this case – goes temporarily offline.
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.
Our present situation warrants a significant level of knowledge humility. We can’t know for sure how future energy systems will function, what they will cost, and the types of societies they will allow, but modelling efforts can provide indications of what is and isn’t possible if given sets of conditions prevail. There are important benefits that come with greater knowledge humility.
The implications for the future of the global economy will not be pretty — but if we face up to it, the transition to more sustainable societies will be all the better for facing reality, rather than continuing with our heads in the sand.
Europe has been the global leader in energy transition for decades, offering to the rest of the world many useful examples of both policies that work and those that don’t. As a result, European countries now have some of the world’s most energy efficient economies, and the largest shares of renewable energy.
This is the second and final part of a recent conversation with Richard Heinberg by Greening the Apocalypse. Greening the Apocalypse is a weekly show on Melbourne’s Triple R 102.7FM.
Global investment in coal-fired power plants is set to decline “dramatically” after passing an all-time high during the past several years, says the International Energy Agency (IEA). That’s one of the most striking messages from World Energy Investment 2017, published today (11th July). The report, now in its second year, offers a comprehensive picture of energy investment from fossil-fuel extraction through to transport, energy efficiency and power networks.
Richard Heinberg joins Juliet Jacobs at BFM radio to discuss realistic avenues for transitioning to renewable energy, the environmental implications of economic growth, and how we can build more resiliency into the sustainability movement.
Shared renewables is a democratic system, in which a community or neighborhood collectively owns or operates small-scale energy systems. The co-owners do not necessarily have to be neighbors — or even live near each other — depending on the type of system.
Of course, some scientific evidence of the technical feasibility of a ‘decarbonization’ of the economy is needed, as this decarbonization requires making policy choices that will have profound and lasting economic and social consequences. However, trying to elaborate detailed technical assessments, scenarios and roadmaps for a move to 80%, 90% or 100% renewables is probably somewhat futile at this stage, and may even obscure rather than inform the conversation that societies, in the U.S. and elsewhere, need to have.
People soon realized it was not enough to just say no. They needed to offer a better alternative and say yes to something. So the Germans demanded what has since become known as energy democracy: the right to make your own energy.
