The young man, who was tall and thin, with sun-streaked fair hair, and a wind- and sun-burned face, who wore the sun-faded flannel shirt, a pair of peasant's trousers and rope-soled shoes, leaned over, put his arm through one of the leather pack straps and swung the heavy pack up onto his shoulders.
Her skin, every follicle and flaw in focus in the ground glass of his lens, had the same sun- and sea-wind weathering, but fainter, of the stones of the Californian desert, and her hips had the convolutions of the naked mountains.
Massive and expensive, most wind and sun-powered innovations have not found a cost-effective way to penetrate those markets.
FORBES: Social Enterprise Spotlight: Portable Solar Lighting
It also has lots of different exposures so there is likely to be sun or powder or wind-loaded snow somewhere.
Because geothermal produces consistent, base-load power--it doesn't depend on the wind blowing or the sun shining--utilities will pay up to three times more for geothermal electricity than for electricity from an intermittent source, like wind.
The Sun's magnetic field and solar wind - mainly in the form of electrons and protons coming out of the Sun - protects the entire Solar System by acting as a sort of shield from cosmic rays (very energetic particles and radiation from outer space).
"When they come close to the Sun, this ice melts - solar wind blows this material out into space, so you get a tail of matter coming off the comet, " explains O'Brien.
Some foresee hybrid wind-gas and solar-gas plants, with gas producing electricity when sun and wind are weak.
ECONOMIST: What bigger estimates of America��s reserves could mean
Investing in clean British energy from the wind, waves and Sun - along with a major energy-saving drive - would create hundreds of thousands of new jobs, boost energy security and keep the lights on.
Above all, be prepared for wind, sun and nights of bone-chilling cold.
Deep into the autumn, every package or can I open takes me back to conversations around the cookhouse's huge stone fireplace, to wind rustling through alders, and sun-spangled blue-green water, to the promise of adventure every morning.
To that end, green fuels require back-up generation that kicks in when the wind dies down or the sun ceases to shine.
In the quest to tap new sources of renewable energy, scientists are turning to the sun, to the wind, and of course, to a variety of bio-derived fuel alternatives.
Gone were the primeval rainforests, replaced with mile after mile of sun-drenched sugar cane, and grand plantation houses that look lifted from Gone With The Wind (and indeed are occasionally used as movie sets).
But unlike other alternative energy sources, such as sun or wind power, there's nothing fickle about the availability of the key raw ingredients--fresh water and sea water.
