As we explore ways to bring price relief and bolster our country's energy independence, one significant energy source has emerged as a potential solution, hydrogen fuel cells.
The environmental benefits of hydrogen are also outstanding. When used as an energy source, hydrogen produces no emissions besides water. Zero polluting emissions, an amazing advance over the current sources of energy that we use.
And when these advances are made, hydrogen can fill critical energy needs beyond transportation. Hydrogen can also be used to heat and generate electricity for our homes. The future possibilities of this energy source are enormous.
Some solutions are relatively simple and would provide economic benefits: implementing measures to conserve energy, putting a price on carbon through taxes and cap-and-trade and shifting from fossil fuels to clean and renewable energy sources.
Many countries - as well as cities, states and provinces - are taking global warming seriously and are working to reduce emissions and shift to cleaner energy sources.
We've offered direct financial support for a range of renewable energy sources, whether it be large-scale solar, whether it be geothermal, whether it be wave power or wind power.
Goals provide the energy source that powers our lives. One of the best ways we can get the most from the energy we have is to focus it. That is what goals can do for us; concentrate our energy.
If we had a hydrogen economy worldwide, every nation on earth could create its own energy source to support its economy, and the threat of war over diminishing resources would just evaporate.
Life is extremely resilient once it takes hold, but it requires rich chemistry, large energy sources, and stability, right from the beginning. The comparative planetology of our solar system makes it seem like those initial conditions are hard to come by.
The medical nanobots in my novel 'Small Miracles' tap the energy sources that the patient's own body provides. That is, they can metabolize glycerol and glucose, just as the cells in our bodies do.
