AC vs. DC Powerlines and the Electrical Grid
powerlines
This post explaining some important differences between high voltage AC and high voltage DC power transmission options. It is part of a series explaining the options for building out a transmission Supergrid.[read more]
Computers and Appliances: Today's Home-Based Energy Hogs
The Energy Information Administration is touting the fact that “heating and cooling” now comprise less than half of our residential energy usage. But that’s only half the story.[read more]
Energy Efficiency First, Renewables Later
The usual custom among energy systems analysts is to make projections regarding future energy consumption and work back from those projections to what is required to meet them. Following business-as-usual practices, Brussels projects a doubling of Europe’s energy consumption by 2050, and that 60-80% of the energy generation in 2050 will...[read more]
Smart Grid Needs Smart Buildings and Policy
Buildings consume an extraordinary amount of energy in the USA. Commercial, industrial, or residential expend their energy in different categories, but numerous studies have shown that energy efficiency and intelligent building technologies reduce energy bills. Not only that, but smart buildings can have a strong multiplier...[read more]
Overlooked Tax Deduction for Energy Efficiency Projects
Leaving money on the table is never a good thing in business. It is however common practice for companies, landlords and others involved in Green Energy Projects. In short the owners of buildings simply are not taking advantage of the Energy Policy Act of 2005 Section 179D which allows for up to a $1.80/sf deduction for...[read more]
Top Energy Efficient Tax Credits
Improve the energy efficiency of your home and tax money at the same time with these energy efficiency tax credits: 1. Fuel CellsFuel cells are an incredibly exciting technology that many people do not know about. A fuel cell is an electrochemical device that converts chemical energy into electricity. More technically, fuel cells use...[read more]
Combining HVAC and Energy Storage Cooling in EVs
As this blog has noted before, PEEM (Power Electronics and Electrical Machine) technology is essential with electric-drive vehicles. PEEM technology comprises three main elements: power electronics (e.g., boost converters and inverters); electric motors; and thermal control and system integration. And, thermal control is a critical...[read more]

“Negative pricing if it was wide spread it would be quickly fixed by the utilities who would simply choose to dunp excess electricity via perhaps joule heating rather than sell it at a loss.”
“These artificial leaf researchers get lots of headlines, but could they really be cost competive with normal solar panels connected to normal electrolysis units? Interconnecting a large area with plumbing for water and hydrogen will like cost more than interconnect with electrical wire. Then there is the giant lead in efficiency that normal PV solar cells have over these new PEC ...”
