A Quote by Tulsi Tanti

Coal, oil and natural gas have lit homes and powered machinery for centuries, driving civilization forward. But as human development accelerated, the unsustainability of such energy became apparent.
The transition from coal, oil, and gas to wind, solar, and geothermal energy is well under way. In the old economy, energy was produced by burning something - oil, coal, or natural gas - leading to the carbon emissions that have come to define our economy. The new energy economy harnesses the energy in wind, the energy coming from the sun, and heat from within the earth itself.
There's no question that natural gas is a lot better than coal or oil, in the sense that natural gas produces less carbon per unit of energy produced.
We've recognized that natural gas would be the fastest-growing of the conventional fuels: oil, natural gas, coal. And so, we see the important role that natural gas will play globally and, more importantly, the important role it will play in the U.S. in terms of meeting future energy demand.
Today, natural gas now outstrips coal as the leading provider of electricity in America. If this is as big as people believe it is, natural gas will soon be powering trucks and marine ships. Maybe even standard commercial cars that people use at home through compressed natural gas, other gas to liquids. The potential is there for more energy independence by America and a reliance on cleaner fuel - natural gas emits half as much as coal, in terms of carbon emissions. That's a real bounty.
Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner - methane is far more potent a greenhouse gas than carbon dioxide - it can wipe out all the advantages of natural gas over coal.
Electricity is derived from many non-renewable energy sources like oil, natural gas and coal.
We simply have to transition from an economy based almost exclusively on oil and coal and natural gas to one that's far more diversified, that uses solar energy, and wind energy, and the power of the tides, and bio-mass energy, and eventually, develops hydrogen.
One point I like to stress is that we should think of coal, oil, natural gas, and nuclear, as clean energy.
Exceptional circumstances can accelerate the gradual process of energy transitions: France's decision to develop nuclear energy on a grand scale is perhaps the best example of how that can be done by government fiat. In contrast, America's accelerated shift from coal has been driven by an inevitable embrace of cheaper natural gas.
We do have serious energy needs for the country, we are aware that natural gas is especially in demand because of its air quality benefits: 90 percent of new power plants have been natural gas-powered.
There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.
We have to slow down the emissions of carbon dioxide and methane from coal burning, oil and eventually natural gas... And the best ways to do that are energy efficiency and a switch to renewables.
The total amount of energy we use every year - from coal, oil, natural gas, hydro, nuclear, and everything else - is dwarfed by the amount of solar energy hitting the planet each year.
How did we make the transition from using wood to using coal, from using coal to using oil, from using oil to using natural gas? How in God's name did we make that transition without a Federal Energy Agency?
I understand the impact of those kinds of factors on job creation. I will have a very different policy. My policy on energy is to take advantage of coal, oil, natural gas, as well as our renewables, and nuclear - make America the largest energy producer in the world.
Coal used to be a very dirty fuel but coal has become cleaner and cleaner over the decades. Clean coal now is quite clean. Clean coal now has the same emissions profile as natural gas. Clean coal can become cleaner still. We can take even more of the pollutants out of coal and I believe we should. Clean coal, I think, is the immediate answer to Canada's energy needs and the world's energy needs. There are hundreds of years available of coal supplies. We shouldn't be squandering that resource. We should be using it prudently.
