The Internet is, in effect, a grid that dispenses applications rather than electricity.
Two are university programs, like AguaClara, a research program at Cornell University that produces municipal water treatment technology which relies on gravity rather than electricity.
Rather than create electricity by heating water and turning a turbine, Wilson's new reactor would use nuclear fission to produce energy from molten salt.
For a very large part of the energy requirement of such centres (other than one Facebook one which was deliberately placed in near Arctic conditions) is that necessary cooling, rather than the electricity demands of the computing itself.
Traders would love to turn the risks faced by suppliers, transmitters and retailers of electricity into financial products, so that they could hedge the hazards of weather, fuel supply and wind, and settle up in cash rather than in actual electricity.
ECONOMIST: Is there life after Enron in Europe's power markets?
The Electromagnetic Railgun (EMRG) is a high-risk, yet high-payoff technology that uses electricity rather than chemical propellants to launch projectiles.
Rather than going global, electricity bosses should perhaps concentrate on efficiently shrinking their domestic business and returning cash to shareholders.
Natural gas has been so cheap that utilities have turned to it to generate electricity, rather than contemplate building multibillion-dollar reactors.
Rather than relying on fire, electricity or natural gas, chefs at El Diablo heat their meat over a still-active volcano.
The brakes also serve to send energy to the batteries, recapturing energy from friction and regenerating electricity, rather than allowing the energy to dissipate as heat.
FORBES: 2013 Ford Fusion Energi Test Drive And Review: Plug It In And Go
In a running skirmish with Brian Wilson, the energy minister, he has argued that renewable-energy schemes should be properly costed and subsidised rather than propped up by fudged electricity prices.
ECONOMIST: Sir Howard Davies is a hard act for Callum McCarthy to follow
Natural gas is becoming more cost-competitive with coal, but conservatives want the market, not politicians and bureaucrats, to determine when it makes sense to produce more electricity from natural gas rather than coal.
FORBES: Will Ted Cruz's Primary Victory Finally Awaken Florida's Establishment Republicans?
City leaders promised businesses access to high-quality, high-reliability sources of electricity if they located in Stamford rather than neighboring cities in New York and New Jersey.
Another is to allow local people to be able to choose low-carbon local energy sources, rather than being obliged to rely on large-scale electricity grids run on polluting coal.
Secondly, when considering end-to-end efficiency, it is much less energy-intensive to heat water by direct use of natural gas on-site, rather than by using that natural gas to first make electricity that is used to heat water because of the large conversion losses at power plants.
These are going out of fashion because they convert too much of the electricity passing through them into heat, rather than light.
He also predicts that Petrobras will end up flaring much of the gas that rushes out with the oil, rather than spending lots of money to liquefy it to generate electricity.
Depending on the delta between the price of electricity stored and the price of electricity avoided by using the stored kilowatts rather than power from the grid, the investment in an eneGoon system could be a slam dunk.
Electricity generation becomes a net absorber of CO2 rather than a net emitter.
The location of those data centers is important, Greenpeace argues, because data centers -- basically big warehouses full of computers that store data "in the cloud" or online rather than on home machines -- are such big users of electricity.
And Ms. Olivo struggled to understand the electricity bills until she realized that provider Potomac Edison was mischarging the family by adding, rather than crediting to the bill, the energy produced by their solar panels.
