What happens when the wind doesn’t blow? The North Sea, locale of the world’s largest cluster of wind farms, normally delivers strong, consistent wind flows that keeps the turbines spinning. But every once in a while, weather happens and the winds diminish. That’s what’s occurring now. Blame it on global warming, if you will — that seems to be the explanation for every inconvenient fluctuation in rainfall, temperature and extreme weather.

Whatever the cause, according to the Wall Street Journal, the falloff in wind is wreaking havoc in the United Kingdom, where wind supplies 25% of the nation’s electric power. Due to the wind “shortage,” marginal electricity prices have shot up to the equivalent of $395 per megawatt/hour (or $0.395 per kilowatt hour). That compares to the statewide average of $0.11 per kilowatt hour in Virginia. To make up the deficit, UK utilities have been burning more… coal. Coal will provide a backstop until 2024, when all coal-fired plants will be shuttered. Is anyone in Virginia paying attention?

Speaking of coal… Southwest Virginians are still casting around for ideas of what to do when the coal plants close. There is no lack of creative thinking. I just don’t know how practical it is. Here is the latest: growing artisanal grains. Once upon a time, Virginia’s coal counties grew grain to supply alcohol feedstock for a booming coal-town bars and saloons. The economics shifted in favor of massive Midwest farms, which enjoyed economies of scale, and local grain farming nearly ceased. But, according to The Virginia Mercury, local economic-development groups want to play on the local-food movement to make Southwest Virginia a primary source of specialty grains for Virginia’s growing craft beverage industry. Virginia imports 400,000 bushels of grain into the state. Snagging  a piece of that action could support a lot of farms.

With climate change, who knows how that will work out. Let’s hope the rain keeps falling. Continue reading →

The world economy is rapidly electrifying. Driven by new technologies and the environmentalist push to decarbonize the economy, an increasing share of the energy Americans consume will come out of the electric socket, reports the Wall Street Journal in a special report. “Instead of having fuels like natural gas or oil or gasoline flow directly into our homes, offices, manufacturing facilities and cars, those fuels — and other sources of energy — will increasingly be converted to electricity first.”

A Princeton University study finds that electrifying buildings and transportation could double the amount of electricity used in the United States by 2050, lifting electricity’s share of total energy from about 20% today to close to 50%.

Electrification offers the ability to harness renewable power sources, primarily wind and solar, to displace carbon fuels that contribute to global warming. But it does present the challenge of maintaining the integrity of the electric grid in the face of natural disasters, cyber attacks, and other challenges. While many environmentalists consider global warming to be an existential threat to humanity, a collapse of the electric grid accounting for 50% of all energy consumption would pose an equally existential threat to human well being — within the next two or three decades, not by the end of the century.
