We Need Nuclear-Powered Airplanes, Not Solar-Powered Ones

We Need Nuclear-Powered Airplanes, Not Solar-Powered Ones | Sustainable Energy | Scoop.it

It’s being billed as a triumph for solar power, but the Solar Impulse solar-powered airplane could also be seen as an illustration of just how amazing liquid fuels like jet fuel are, and how far solar power and battery technology would need to go to challenge them. A far better idea than solar-powered flight is nuclear-powered flight, although I don’t mean putting nuclear reactors on airplanes as the U.S. government once proposed (see these two pdfs). Let’s use fission to make low-carbon fuel.

In Japan, energy saving takes its toll

In Japan, energy saving takes its toll | Sustainable Energy | Scoop.it

Japan's shutting down its nuclear reactors 'overnight' proves increasingly challenging, as goodwill for draconic energy conservation measures fades. And the shutdown has resulted in massive increased imports of fossil fuels.

UK opposes 2030 renewable energy target

UK opposes 2030 renewable energy target | Sustainable Energy | Scoop.it

The UK government wants nuclear power to be given parity with renewables in Europe, in a move that would significantly boost atomic energy in Britain but downgrade investment in renewable generation, according to a leaked document seen by the Guardian.

Should the Department of Energy Fund Small Modular Reactors?

Should the Department of Energy Fund Small Modular Reactors? | Sustainable Energy | Scoop.it

Small, modular nuclear reactor designs could be relatively cheap to build and safe to operate, and there’s plenty of corporate and government momentum behind a push to develop and license them. But will they be able to offer power cheap enough to compete with natural gas? And will they really help revive the moribund nuclear industry in the United States?

Solving the next energy crisis, a million houses at a time | SmartPlanet

Solving the next energy crisis, a million houses at a time | SmartPlanet | Sustainable Energy | Scoop.it

Instead of building a new, $17 billion nuclear power plant, Mathis showed how $5,000 worth of energy-efficiency upgrades to each of the state’s 4 million homes would save twice as much power as the new nukes would generate, and create hundreds of thousands of jobs installing insulation, air sealing, replacing windows, sealing leaky ducts, and the like.

Can Efficiency Counter a Loss of Nuclear Power?

Can Efficiency Counter a Loss of Nuclear Power? | Sustainable Energy | Scoop.it

That argument is particularly common in New York State and in Vermont, where state governments are trying to close nuclear reactors within their borders. So, how effectively can efficiency replace a reactor, making up for the loss of this zero-carbon energy source?
