Combining Energies

A hot shower, even where there is no electricity: low-income families in Argentina build their own solar water heaters using recycled materials. A non-profit organization hosts the workshops, gathers helpers and shows participants how to utilize renewable energy.

Is 100% Renewables Realistic?

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?

100% Renewables – A Few Remarks about the Jacobson/Clack Controversy

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.

UN Renews Call for Site C Dam Review to Protect National Park

The UN’s World Heritage Committee has once again demanded that the federal government conduct a proper assessment of the downstream impacts of British Columbia’s controversial Site C dam on Wood Buffalo National Park. In addition, the committee has asked the Trudeau government to immediately implement recommendations to protect the park, home of the Peace-Athabasca delta — the largest inland freshwater delta in North America — from industrial development..

Using Energy to Extract Energy – the Dynamics of Depletion

We now have to take into account that depletion means that, at well heads around the world, the energy to produce energy is increasing. It takes energy to prospect for oil and gas and if the wells are smaller and more difficult to tap because, for example, they are out at sea under a huge amount of rock. Then it will take more energy to get the oil out in the first place.

Different Strokes for Energy Transitions

In this episode, we have a wide-ranging talk with Dr. Benjamin Sovacool of the University of Sussex about a tiny fraction of his voluminous research on energy transition topics, with a focus on the speed of energy transitions; the ways that the Nordic countries of Denmark, Finland, Sweden, Norway and Iceland are going about their transitions; his outlook for CCS technology and nuclear power; and the potentials and pitfalls of nuclear power and the potential for distributed energy resources to displace nuclear…

Standing Rock Sioux Claim ‘Major Victory’ in Dakota Access Fight

A federal judge has ruled that the Trump administration’s approval of the controversial Dakota Access Pipeline violated federal law in certain critical respects and has ordered the Army Corps of Engineers to reconsider parts of its environmental analysis. The decision marks the first legal victory of the Trump presidency for the Standing Rock Sioux, which have been fighting the pipeline for nearly a year.

Coal Is a Dinosaur and so is the Growth Economy

What does this downgrading of likely carbon emissions mean for climate change modelers, climate activists, policy makers, and concerned citizens? According to Ritchie, the implication is clearly not as simple as “don’t worry, fossil fuel depletion will solve climate change for us.”

Why Is Trudeau Blowing His Chance to Curb Dangerous, Climate-Warming Methane?

Here’s what the Trudeau government definitely knows about the science of methane. The gas accounts for more than one-quarter of all global warming, and reliable data from satellite and airplane surveys show that emissions are increasing, largely from the oil and gas industry.
