Running appliances off DC power can cut energy consumption dramatically by reducing the number of AC-DC conversions.
Inverters and microinverters convert the direct current (DC) power produced by solar panels into alternating current (AC) used in homes and businesses.

The reserve power category includes backup batteries and related products that provide a continuous supply of direct current (DC) during power outages.
Indeed, Andy Petro of NASA's technology office in Washington, DC, says power beaming might change the economics of space exploration completely.
High-voltage DC can carry power over long distances at lower cost than alternating current, but the transformers still cost too much to make the idea widespread.
The NYT reviewer, John Broder, wrote that during the test drive from Washington DC to Connecticut, the power had drained sooner than expected, forcing him to turn down the heating and drive below the speed limit.
To me, it seems the choice is obvious, the FairTax, bringing the single greatest transfer of power OUT of DC and back TO the people and economic prosperity or continue with the same old, same old and keep getting the same results!
Since batteries, solar panels and computer components are all DC devices anyway, efficiency is increased and less power is lost along the way.
Electricity leaves the power plant as AC and gets converted to DC for powering laptops, for example.
FORBES: Google-backed Transphorm Raises $25M For Power Conversion Tech
To achieve this power savings, rivals need to add external dc-to-dc converters, increasing both the size and cost of their products.
Since the late 1990s, a seismic shift has occurred, in which the candidates themselves are becoming irrelevant as Political Action Committees, party committees, and Independent Expenditure committees have become more dominant, strengthening the power of the political class and the insider and DC elites who work on their own or in concert with party functionaries.

The technology also can sit in DC-to-DC devices, which are designed to adjust the voltage and minimize power losses.

The portable programmer, which plugs into the DC port under the locks, can also open any door, even providing power through that port to trigger the mechanism of a door lock in which the battery has run out.

"Turn the power off and get out and contact the fire service, " said DC Lennard.

Once completed it is expected to generate 6.4 MWh DC (equivalent to 5MW AC) and be capable of generating enough electricity to power about 700 average-sized homes.
Whether they work inside the corridors of power or outside them, all religious-freedom advocates in Washington, DC, find they have to make pragmatic arguments as well as moral ones.
Solar panels produce electricity in DC, which needs to transform into AC for feeding the electric grid or for using the power onsite.

Obama is the only president in recent memory never to have successfully placed a nominee on the DC Circuit, which handles many high-profile appeals, including executive authority to fight terrorism and broader congressional power.
Today, Enterprise offers roughly 300 electric cars (including the Nissan Leaf, Chevy Volt and Toyota Plug-in Prius) and about 3, 200 hybrids (which run on both gasoline and electric power) throughout the United States, including California, Hawaii, Seattle, New York and Washington DC.
Or wander a little further afield to Georgie's namesake: Washington, DC, is only an hour away from the Inn, meaning there's always some fine dining and political power lunching within reach.
