It's commonly known that certain diseases are linked with occupations like lung disease in coal miners.

Decades of working over coal fires in tight, closed spaces with little fresh airto ensure his dishes would not get col had fatally damaged his lungs.

There are still some public lands that contain oil, coal and other natural resources.

This is similar to what's happening in the coal and oil industries, a situation that fuels much of the current political discontent in this county.

Unfortunately, the current low prices for oil, gas, and coal may provide little incentive for research to find even cheaper substitutes for those fuels.

The prices of coal are low as a result of over-supply and decreasing demand.

Renewables account for only a small share of global primary energy consumption, which is still dominated by fossil fuels—30% each for coal and oil, 25% for natural gas.

Natural gas and coal—also fossil fuels—have similarly seen price declines that look to be long-lived.

Coal prices also are low, owing to over-supply and the scaling-down of demand, especially from China, which burns half of the world's coal.

Coal and natural gas are mainly used for electricity generation, whereas oil is used mostly to power transportation, yet the prices of all these energy sources are linked.

The treaty banning mining here, shielding 116 coveted ( ' , 令人垂涎的) reserves of iron ore, coal and chromium, comes up for review in 2048.

Whether it is a transition from imported to domestic oil or from coal-powered electricity production to natural-gas power plants, politicians love to talk big.

When you hear people speaking of making a rapid transition toward any type of energy, whether it is a switch from coal to nuclear power, or a switch from gasoline-powered cars to electric cars, or even a switch from an incandescent to a fluorescent light, understanding energy system inertia and momentum can help you decide whether their plans are feasible.

Some coal power plants in the United States have operated for more than 70 years! The oldest continuously operated commercial hydro-electric plant in the United States is on New York's Hudson River, and it went into commercial service in 1898.

It is one thing to say that we are going to shift 30 percent of our electricity supply from, say, coal to nuclear power in 20 years.

That’s energy in all forms--oil, gas, coal, nuclear, solar and even wind power.

Dakota Gasification of North Dakota captures CO2 at a plant that converts coal into synthetic natural gas.

Some propose storing the CO2 in coal mines or liquid storage in the ocean, Shell favors storing CO2 in deep geological structures such as saline(鹽的) formations and exhausted oil and gas fields that exist throughout the world

Lending is the coal to our engine, so we want to make more loans.
