A Quote by Ramez Naam

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.

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.

Thomas Friedman

Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.

Bill Nye

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.

Lester R. Brown

Of course methane is a fossil fuel, but as long as it is burned efficiently and fugitive emissions of methane gas are minimised, it is a less harmful fossil fuel than coal and oil and is an important way-station on the global journey towards low-carbon energy.

Mark Walport

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.

Thomas Friedman

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.

Katharine Hayhoe

Whether it is to reduce our carbon-dioxide emissions or to prepare for when the coal and oil run out, we have to continue to seek out new energy sources.

Martin Rees

Alongside energy efficiency, renewables and abatement, I believe safe nuclear power, with manageable waste, can play an important role in reducing greenhouse gas emissions, as long as it is cost competitive with other low carbon generation.

Ed Davey

'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.

James Hansen

Britain needs a diverse energy mix - home grown renewables, new nuclear, a switch from dirty coal to cleaner gas, and, when the technology is ready, carbon capture and storage. Diversity will keep the lights on and ensure we go green at the lowest possible cost.

Ed Davey

Our leaders must get to grips with the huge risk that carbon dioxide emissions pose to the economy and the environment. As we know, carbon dioxide is a long-lived gas. It hangs around.

Jose Angel Gurria

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.

Mitt Romney

The more traditional fuel sources we have relied on as a nation - coal, oil, and natural gas - I'm hoping they can allow us the financial springboard to move to the next generation of energy sources: renewables and alternatives.

Lisa Murkowski

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.

William J. Clinton

One of the reasons the United States has actually been reducing its emissions in recent years is actually that there's been a boom in natural gas. It's displacing coal. It emits less carbon dioxide when you burn it. This is not really an Obama policy. It's just something that happened because of technology and the free market.
