How much of the world’s energy is supplied by renewables?
How much of the world’s energy is supplied by renewables? BP and the International Energy Agency (IEA) measure the contribution of renewables to the global energy mix in terms of primary energy consumed while the World Bank estimates it in terms of final energy consumed. All three give different results, with BP estimating a total […]
The Cook Islands go solar
The Cook Islands go solar Like a number of other remote island communities, The Cook Islands have decided to get rid of expensive diesel power and go to 100% solar within the next few years. To do this they are constructing solar arrays backed up with small amounts of Li-ion battery storage which they believe […]
Western Grid Regionalization
Western Grid Regionalization California and 12 other US states, plus parts of Canada and Mexico, are considering whether to expand the California wholesale grid and balancing area to include the entire region, in order to increase the flow of reliable, affordable, and renewable power across the West. This shift to a regional independent system operator, […]
As Rest of World Moves Towards Renewables, US Keeps Offering Exclusive Tax Breaks for Fossil Fuels
As Rest of World Moves Towards Renewables, US Keeps Offering Exclusive Tax Breaks for Fossil Fuels About a half decade ago, as the shale drilling rush was sweeping across the U.S., drillers needed upfront cash — and quick — to let them snap up acreage, drill and frack exploratory wells, and hone their skills at […]
A review of recent solar & wind auction prices
A review of recent solar & wind auction prices Recent renewable energy auctions in a number of countries have been won by record low solar and wind bids – proof, according to some media sources, that wind and solar are already cheaper than fossil fuels. This post addresses the question of whether these low bids […]
A brief review of the New England electricity sector
A brief review of the New England electricity sector New England’s transition to renewable electricity is complicated by differences between the generation mixes in and the renewables targets set by its six component states. New England’s approach to fostering renewables by replacing dispatchable fossil fuel generation with wind and solar also does not help. New […]
Photovoltaics? Who in the world would want to spend money on such a silly idea?
Photovoltaics? Who in the world would want to spend money on such a silly idea? The “Solar Roadways” plant in Idaho in an image from the “EmphaseEnergy” site. The performance of this expensive plant is abysmally low and, with the best of good will, I can’t see it as anything but a propaganda stunt to […]
Stunning drops in solar, wind costs mean economic case for coal, gas is ‘crumbling’
Stunning drops in solar, wind costs mean economic case for coal, gas is ‘crumbling’ Things are only going to get tougher for gas and coal compared to renewables. SOLAR POWER PRICES ARE DROPPING AT RECORD RATES. CREDIT: ACERA. Prices for solar, wind, and battery storage are dropping so rapidly that renewables are increasingly squeezing out […]
Not So Happy Motoring
Not So Happy Motoring It hasn’t been a great month for America’s electric car fantasy. Elon Musk’s Tesla company — the symbolic beating heart of the fantasy — is whirling around the drain with its share price plummeting 22 percent, its bonds downgraded by Moody’s to junk status, a failure to produce its “affordable” ($36,000 […]
Alberta’s Aggressive Renewable Energy Push
Alberta’s Aggressive Renewable Energy Push One Canadian province has set its sights on generating almost a third of its electricity from renewable sources by 2030. This will take some US$7.77 billion (C$10 billion) in investments by that year to add 5 GW of renewable capacity, creating more than 7,000 jobs. The province is Alberta—the center […]
Natural Gas Is Under Attack
Natural Gas Is Under Attack Natural gas has been billed as the key “bridge fuel” that will help the energy transition, replacing coal while buying time for renewable energy to scale up. However, even as gas is triumphing over coal in the U.S., it is increasingly under attack by policymakers. Gas claims a carbon emissions […]
The troubling realities of our energy transition
The troubling realities of our energy transition I recently asked a group gathered to hear me speak what percentage of the world’s energy is provided by these six renewable sources: solar, wind, geothermal, wave, tidal, and ocean energy. Then came the guesses: To my left, 25 percent; straight ahead, 30 percent; on my right, 20 […]
Pathways to Deep Decarbonization
Pathways to Deep Decarbonization As energy transition proceeds we’ll need to move well beyond decarbonizing electricity generation and into transportation and space heating powered by renewables. But we’re only beginning to figure out the pathways by which we might do that, and since each region has its own particular sources of renewable energy and its […]
Cornucopian Renewable-Energy Claims Leave Poor Nations in the Dark
Cornucopian Renewable-Energy Claims Leave Poor Nations in the Dark Stanford professor Mark Jacobson and his colleagues have written yet another paperpurporting to show that 100 percent of energy demand can be fulfilled by wind, solar, and hydroelectric generation. This latest study, which comes in the form of a manuscript accepted but not yet published by […]
