A Quote by Steven Chu

The biggest gains, in terms of decreasing the country's energy bill, the amount of carbon dioxide we put into the atmosphere, and our dependency on foreign oil, will come from energy efficiency and conservation in the next 20 years. Make no doubt about it. That's where everybody who has really thought about the problem thinks the biggest gains can be and should be.
We must have a relentless commitment to producing a meaningful, comprehensive energy package aimed at conservation, alleviating the burden of energy prices on consumers, decreasing our country's dependency on foreign oil, and increasing electricity grid reliability.
First, we must stop wasting energy. A quarter of the UK's carbon emissions come from the home. Our housing stock - the oldest in Europe - is costing us the earth... After transport, heating is the second biggest driver of energy demand in Britain. British Gas research suggests that householders who put in energy efficiency measures cut their gas consumption by 44%. Better insulated buildings will do much of the work for us.
We've got to control our own energy. Now, not only oil and natural gas, which we've been investing in; but also, we've got to make sure we're building the energy source of the future, not just thinking about next year, but ten years from now, 20 years from now. That's why we've invested in solar and wind and biofuels, energy efficient cars.
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.
We need to break our dependency on foreign sources of oil, which leaves us at the mercy of foreign powers. To do that, we should increase domestic energy production.
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.
There's no free lunch. If you want an industrial economy, you need energy. If you want energy, it will produce pollution. You can have it in two forms. You can have it dissipated in the atmosphere - like carbon dioxide - which then you cannot recover, or you can have the waste concentrated in one small space like nuclear. That is far easier to deal with. The idea that you can be able to create renewable energy at a price anywhere near the current price for oil or gas or coal is a fantasy.
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.
Well, there's no doubt about the fact that, that higher energy prices lead to greater conservation, greater energy efficiency, and they also, of course, play a useful role on the supply side.
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.
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.
If our country is serious about reducing our dependency on foreign oil, we need to get serious about mobilizing the infrastructure necessary to distribute and dispense the next generation of fuels.
The problem carbon is that everyone thinks we have an energy problem, we don't. We have plenty of energy. We have a carbon problem. Carbon is a material, so we have a material problem, not an energy problem.
What an honor. What a responsibility. What a gift we have been given to be born in an atmosphere with oxygen and carbon dioxide and millions of years and phenotypes cheering us on with recycles of energy.
If I were emperor of the world, I would put the pedal to the floor on energy efficiency and conservation for the next decade.
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences.
