Producing substantial crop yields without greenhouse gas generation from chemical inputs or intensive fossil fuel use is a challenge.

But this approach would still consume too much of the CO2 budget. Even the most modern and advanced conventional coal fired power plants emit over 15 times more CO2 per unit of electricity than renewable energy systems, and more than twice the amount of efficient gas fired power stations.

Thus, nuclear power will halt the decline in government revenues by freeing more oil and natural gas for export. Iran s natural gas resources, if developed, would not be a substitute for cheap nuclear power, because gas is more profitable in other uses than in power generation.

Second, the world s two largest greenhouse gas emitters, the United States and China, are now more committed to action than they were five years ago. US President Barack Obama has announced a far reaching plan that authorizes the Environment Protection Agency to take dramatic measures in the next few months to limit power station emissions, virtually ending coal fired electricity generation altogether.

Much of the future increases in coal fired electricity generation will come from strategically important developing countries like China and India. In 2006 alone, China added about 93,000 megawatts of coal fired electricity generating capacity, and this trend is expected to continue as the country tries to meet its huge energy needs.

He fired again.

Tom was fired.

Other resources like fuel oil, diesel, light crude, solar, and gas are also available as means of electricity generation, but their costs are all quite prohibitive.

He fired. Nothing happened.

If you get fired...

He fired three shots.

Tom should be fired.

Have you been fired?

When was Tom fired?

When was Tom fired?

He may well be fired.

I wasn't fired. I quit.

I was fired without cause.

They should all be fired.

Tom was fired in October.

This is why the OECD Secretary General has suggested that it is time for a moratorium on the construction of conventional coal fired power plants. Governments have far more cost effective electricity generation technologies at their disposal.

Natural gas emits only half as much CO2 as coal, and occupies a rapidly increasing share of electricity generation up 37 since 2007, while coal s share has plummeted by 25 . Indeed, natural gas has drawn close to coal as the number one source of US power.

In the United States, the shale gas revolution, facilitated by the development of hydraulic fracturing ( fracking ), has brought prices to their lowest levels since natural gas gained prominence after the oil crises of the 1970s. With many more countries set to tap shale gas reserves over the next decade, this downward trend will most likely continue, helping to lower the price of electricity generation further.

Some of you haven t fired them yet.

It was crowded, many shots were fired, he adds.

The firing squad aimed, fired the general was dead.

I can choose the next American Idol. You're fired.

I've been told Tom is going to be fired.

Here's your brute force approach. Once you get through your brute force approach, then you just rip off whole mountaintops. And you end up with the single largest source of carbon emissions, which are coal fired gas plants. That is probably not the best use of bioenergy.

Indeed, the joint air monitoring network provides a foundation for the region to develop a sophisticated regional air management program. Furthermore, new coal fired power plants may no longer be allowed on either side of the border, necessitating greater use of natural gas and renewable energy sources.

Gas is a similar issue. Gas is also a biological product. And as you think of gas, well, you're familiar with gas. And here's a different way of mining coal.

At that moment, they fired and shot off my fingers.

That's the piston that was fired out of the floor.

Moreover, most economic models do not account for the externalities related to coal and carbon pollution. For example, a recent report by Trucost estimates that coal fired power generation worldwide may be responsible for around 1 trillion of damage due to climate change and air pollution.

It doesn't tell you whether or not the gas station has gas.

It's a story passed on generation after generation.

We pass it down from generation to generation.

Then one of the soldiers fired into the group of children.

I was fired up I was ready to make a difference.

At first, I felt they were right to have fired me.

He then fired a beautiful through ball, leading Hazard into the box.

As the mission withdrew, the guard fired warning shots into the air.

It's called Gas.
