A Quote by John Olver
Since 1850, burning of fossil fuels, coal, oil and natural gas has increased 100 times to produce energy as the world has industrialized to serve the world's more than 6 billion and growing population.

The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.
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.
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.
The real requirement, if we are to avoid runaway global warming, is probably 80% by 2030, and almost no burning whatever of fossil fuels (coal, gas and oil) by 2050.
If you say the world is totally dependent on oil in many parts of the world, coal and certainly natural gas, we are fossil fuel, that is modernity, modernity has two elements: individualism and oil. Now to move toward a more enlightened sustainable world, we have to transform with lots of technology, with even differences in the way we see the world and how we live in the world. That`s going to take decades.
Under pressure from a growing movement of people who want their money out of fossil fuels, universities, pension investors and foundations are looking to exclude coal, oil and gas stocks from their portfolios.
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.
Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives. - Dr. Carl Sagan
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.
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.
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.
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.
World leaders need to realize that the cost of transforming the global energy system is far less than coping with the consequences of burning the planet's remaining fossil fuels.
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.
We want to see...the efficient production and use of energy, so that the products we produce and the way we produce them pose no threat to the world's natural environment...economic development...so that more and more of the world's population can enjoy...the things which the energy industry supplies...(and) a society in which ideas and knowledge move freely.
