Insight and inspiration in turbulent times.
Compressed air energy storage (CAES) is considered to be an important component of a renewable power grid, because it could store surplus power from wind turbines and solar panels on a large scale. However, in its present form, the technology suffers from large energy losses and depends on natural gas to operate.
A locally based vision of renewable energy generation could eliminate global or national-level domination of the energy infrastructure by a few large players, and thus the concentration of profits in the hands of a very few. It could also reduce our greenhouse gas emissions to very low levels, comparable to the emissions before the industrial revolution.
The impact Trump and company are having on federal clean energy and climate policies goes beyond regulatory rescissions and under-funded and mismanaged programs. Forced to make hard choices the ties that have bound the clean energy and environmental communities are fraying.
The U.S. shale oil industry hailed as a “revolution” has burned through a quarter trillion dollars more than it has brought in over the last decade. It has been a money-losing endeavor of epic proportions.
The immediate energy nightmare in Puerto Rico is gradually winding down, with electrical power now available to about 90 percent of households (some rural areas are still without power). But it’s clear to nearly everyone that a reversion to the island’s previous energy status quo is not a viable option…
Hughes, whose reliable research is cited by the likes of Bloomberg, Nature, The Economist and The Tyee, has been analyzing energy trends for industry and government for more than 30 years. Unlike many environmentalists, Hughes does not believe that a transition to renewables or even reductions in greenhouse gases will be seamless, easy or cheap.
Industry extracts the lowest-cost, highest-quality, least emissions-intensive fossil fuel resources first. Knowing that fossil fuels will likely be needed for a long time to come, and that producing them is very emissions-intensive, Canada’s current de facto strategy of selling them off at rock bottom prices with declining revenues to government makes little sense.
At the most foundational level, however, there are just two sources of energy. Two sources provide more than 99 percent of the power for our civilization: solar and nuclear. Every other significant energy source is a form of one of these two. Most are forms of solar.
Does climate change pose such an imminent threat to the planet that it’s okay to break the law in order to stop it? Four climate activists currently awaiting trial in Minnesota for shutting off a tar sands pipeline think so — and on Monday, the Minnesota Court of Appeals agreed that they should be allowed to make that argument before a jury when their case goes to trial.
Over the past few years, an international team of climate scientists, economists and energy systems modellers have built a range of new “pathways” that examine how global society, demographics and economics might change over the next century. They are collectively known as the “Shared Socioeconomic Pathways” (SSPs).
With the era of cheap fossil fuels coming to a close, what’s left as low-cost fuel is wood and that had to be the target of the next wave of exploitation. Naively, I was thinking that the rush to wood would have taken the form of desperate people moving to the woods with hand-held axes, but no, in Italy it is coming in a much more destructive way.
Researchers estimate that the global fossil fuel industry is subsidised to a tune of $5.3 trillion (6.5% of global GDP) every year yet this raises few eyebrows. We believe that subsidies for energy access related projects are not an outlandish proposition and in fact, if implemented correctly could be the catalyst that tips the nascent rural off-grid sector into rapid scalability.
