I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.
The use of solar energy has not been opened up because the oil industry does not own the sun.
We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy - sun, wind and tide. ... I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.
Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of ... permanent renewable energy sources, like solar power.
This curious faith is predicated on the notion that we will soon develop unlimited new sources of energy: domestic oil fields, shale oil, gasified coal, nuclear power, solar energy, and so on. This is fantastical because the basic cause of the energy crisis is not scarcity: it is moral ignorance and weakness of character. We don't know how to use energy or what to use it for. And we cannot restrain ourselves. Our time is characterized as much by the abuse and waste of human energy as it is by the abuse and waste of fossil fuel energy.
Mostly, I spend my time being a mother to my two children, working in my organic garden, raising masses of sweet peas, being passionately involved in conservation, recycling and solar energy.
I urge individuals around the world to stand up, and ask local leaders, if they haven't already, to pledge to purchase cleaner cars, build green facilities, and buy green power like wind or solar energy. Our actions may determine if we become a casualty in the war for a habitable planet for generations to come.
We live in a world bathed in 5,000 times more energy than we consume as a species in the year, in the form of solar energy.
The primary means of energy generation is going to solar. It will at least be a plurality, and probably be a slight majority in the long term.
You could power the entire United States with about 150 to 200 square kilometers of solar panels, the entire United States. Take a corner of Utah... there's not much going on there, I've been there. There's not even radio stations.
So, there's quite a big keep-out zone, and when you factor the keep-out zone into account, the solar panels put on that area would typically generate more power than that nuclear power plant.
We have this handy fusion reactor in the sky called the sun, you don't have to do anything, it just works. It shows up every day.
I think the future for solar energy is bright.
The sunlight ... that strikes Earth’s land surface in two hours is equivalent to total human energy use in a year. While much of that sunlight becomes heat, solar energy is also responsible for the energy embodied in wind, hydro, wave, and biomass, each with the potential to be harnessed for human use. Only a small portion of that enormous daily, renewable flux of energy will ever be needed by humanity.
What do oil company executives, vampires and NASA bureaucrats all have in common? They fear solar energy.
I have no doubt that we will be successful in harnessing the sun's energy... If sunbeams were weapons of war, we would have had solar energy centuries ago.
If Earth ever suffers a runaway greenhouse effect (like what has happened on Venus), then our atmosphere would trap excess amounts of solar energy, the air temperature would rise, and the oceans would swiftly evaporate into the atmosphere as they sustained a rolling boil. This would be bad.
Is the warming unprecedented? Probably not. There is abundant historical and proxy evidence for both hotter and cooler periods in human history. Is it our fault? Again, maybe. The correlation of increasing warmth with increasing carbon dioxide concentrations is particularly weak; that with solar energy and with ocean movements is much stronger.
Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the pant's unique ability to synthesize them from sunlight.
The wealth of any ecosystem is its perennials. The primal herbivore-predator-disturbance-rest dance is literally the breath and pulse of the earth. Grasses recycle oxygen far more efficiently than trees. The turnover is faster. Grass reaches out and turns solar energy into carbon. Tillage hyper-aerates the soil, burning out carbon. But because a plant creates bilateral symmetry at the soil horizon, it sloughs off root mass when the top gets chopped off.
