A Quote by James Hansen

What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile.

Bitumen is junk energy. A joule, or unit of energy, invested in extracting and processing bitumen returns only four to six joules in the form of crude oil. In contrast, conventional oil production in North America returns about 15 joules. Because almost all of the input energy in tar sands production comes from fossil fuels, the process generates significantly more carbon dioxide than conventional oil production.

Thomas Homer-Dixon

Tar sands oil is the dirtiest fuel on Earth. Because producing it consumes so much energy, a gallon of tar sands crude generates 17 percent more carbon pollution than conventional crude oil.

Frances Beinecke

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.

Ramez Naam

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

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

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

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

Burning fossil fuels emits carbon dioxide. And carbon dioxide is a greenhouse gas that traps heat in the atmosphere. There is no debate about that. The link is as certain as the link between smoking and cancer.

Christine Todd Whitman

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

Solving climate change is a complex topic, but in a single crude brush-stroke, here is the solution: the price of carbon dioxide must be such that people stop burning coal without capture.

David J. C. MacKay

The carbon emissions from tar shale and tar sands would initiate a continual unfolding of climate disasters over the course of this century. We would be miserable stewards of creation. We would rob our own children and grandchildren.

James Hansen

The process to generate energy using the Canadian tar sands is particularly dirty, producing one of the most noxious fossil fuels on the planet and leaving a devastated landscape in its wake.

John Delaney

On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation on Earth because it has been burning it from the dawn of the Industrial Revolution.

James Hansen

The idea that carbon dioxide is a carcinogen that is harmful to our environment is almost comical. Every time we exhale, we exhale carbon dioxide. Every cow in the world, you know, when they do what they do, you've got more carbon dioxide.

John Boehner

Here's the problem - carbon dioxide doesn't contribute to smog and isn't a health threat. All of this is being done because some people believe carbon dioxide is causing global warming, and that preventing carbon dioxide from entering the air is the only answer. Never mind that there is still an ongoing scientific debate about global warming itself, and that some respected climate scientists believe that methane is a better target, California legislators have locked their sites on carbon dioxide.

Kenneth P. Green

When you buy carbon offsets, you pay to take planet-warming carbon dioxide out of the atmosphere in exchange for the greenhouse gases you put in. For example, you can put money toward replanting trees, which absorb carbon dioxide from the atmosphere.
