Renewables Tie Nuclear in Primary Energy Production

But not quite the way you may imagine

Renewables Tie Nuclear in Primary Energy Production

Energy Daily reports, based on information in a recent issue of the U.S. Energy Information Administration's Monthly Energy Review, that renewables matched nuclear reactors in U.S. primary energy production during the first nine months of last year, each contributing about 11 percent of the total. But if you think this means wind and solar are about to surpass nuclear in generating the country's electricity, you have another think coming.

Remember that primary energy includes all energy, not just electric power, and that renewables as defined by EIA include hydropower and biomass, among other things. Specifically, biomass and biofuels accounted for 52 percent of the renewables share in primary energy production, and hydropower for 31.5 percent. Wind made up 11.5 of the renewables share, and solar less than 1.5 percent.

To be sure, solar energy was the fastest growing renewables component, increasing nearly 50 percent in the first three quarters of last year--but it's still growing from a very small base, with uncertainty as to whether declining PV costs reflect real technological progress or just a shift in production to lower labor cost producers, notably in China.

With enormous potential still untapped--on the Great Lakes, among other places--wind seems destined to still dominate the U.S. renewables picture as far as electricity generation is concerned. Biofuels will remain a dubious contender in transportation: Energy inputs are large, and only modest decreases in greenhouse gases are achieved by comparison with gasoline, if any.

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
