Sure, at one time in history (and today in subsistence cultures) nearly 100% of employment was anchored in fuel jobs: food for humans and their animals, and fuel for heat and cooking.
FORBES: Clean Energy Driven Job Growth Is A Return To The Stone Age
With sorghum, the ethanol distillery can put the bagasse (plant stalks) to use as a boiler fuel, generating heat for distillation and steam for electricity.
Would we be better off if we could run our cars on water rather than gasoline, and fly our airplanes without any fuel, and heat our homes with sunlight?
If you are using a charcoal or wood fire, bank it to one side of your grill and keep the fire as low as possible, starting with just enough fuel to get heat, about 15 briquettes or the equivalent in hardwood charcoal.
When co-generating heat and electricity, solid oxide fuel cells can reach combined efficiencies upwards of 85%, which is excellent, but no word yet whether or not the Bloom fuel cell will co-generate heat.
FORBES: The Economics of Bloom Energy's 'Breakthrough' Fuel Cell
Legge notes that newer fossil fuel plants use the heat that was once wasted to turn an extra steam turbine, a process known as combined cycle.
It can be used to run an internal combustion engine in a car or power one using a fuel cell, with heat and water as the only emissions.
ECONOMIST: Chicken feathers could provide a high-capacity store
Households with oil-fired central heating, and those using solid fuel or liquid petroleum gas to heat their homes, are much more likely to be in fuel poverty than "on-grid" households.
The ponds cool the fuel - which generates intense heat - and provide shielding from radiation.
They cool the fuel - which generates intense heat - and provide shielding from radiation.
The remaining two-third of the energy contained in the fuel is lost as waste heat.
Thermal efficiency is how much of the potential heat energy of the fuel used is actually returned as work at the wheels.
The enormous heat generated by the radioactive fuel in the reactor core needs a constant flow of cold water.

The only emissions from the fuel cell itself are water and waste heat, which can be captured and put to use.
Say, LED bulbs, combined heat and power boilers, fuel cells, whatever.
After all, most heat comes from combustion of a fuel, and biomass is the only renewable and combustible fuel.
Generators powered by fuel cells quietly whir and produce half the heat of diesel as they combine hydrogen with air to create electricity.
Ferrari hopes that the heat generated by all those events will fuel bidding at Maranello.
Thermoelectric coupling uses heat from the decay of a radioactive fuel (as opposed to the full-scale nuclear fission which powers a reactor on Earth) as its energy source.
ECONOMIST: A more efficient way to make electricity in spacecraft
Then it's pumped back in to carry more heat away from the plant's fuel rods, which continue producing energy long after the chain reaction at the heart of the units has been stopped.
It develops anaerobic digesters that convert organic waste into biogas used to generate electricity, heat, natural gas and motor vehicle fuel (CNG). quasar already operates eight facilities in Ohio, and several more are in process in the Buckeye State and elsewhere.
What would happen if policymakers decide to take some of the heat off the industry when it comes to fuel economy?
FORBES: How Cars Will Change If America Becomes The New Saudi Arabia
The three options are to export the waste, use heat treatment or make the waste into a fuel which would then be exported.
The advantage of solid oxide fuel cells running so hot is that all that waste heat can potentially be put to good use.
FORBES: The Economics of Bloom Energy's 'Breakthrough' Fuel Cell
Such aerosol-induced clouds, however, would have silver linings if they formed near a hurricane because the rising air that created them would carry away heat that would otherwise be sucked in to fuel the storm.
Among the energy-saving options, two promising technology switches are the electrification of transportation (electric vehicles can be about four times as energy-efficient as standard fossil-fuel vehicles) and the use of electric-powered heat pumps to deliver winter heating and hot water (heat pumps can be four times as energy-efficient as standard heaters).
The more sophisticated missiles are programmed to steer towards heat (such as that given off by a fuel-burning jet).
Not just for heat and power generation, but as a key transportation fuel.
FORBES: Guest Column: The Shift To Natural Gas Vehicles Is Happening
The new regulations in Massachusetts, which will take effect in June, will promote smaller and more efficient combined-heat-and-power biomass facilities that require less fuel and have lower net carbon dioxide emissions over time.
FORBES: Massachusetts Addresses "Biomass Loophole" and Limits Subsidies
While that argument makes the alarmist blogs and MSNBC, it neglects that, everything else being equal, if hurricanes are becoming rainier, they must be getting stronger, as the fuel that drives the kinetic whirl of the tropical cyclone is the heat released by the condensation of water.
