Consumer Energy Expenditures are 5% of Disposable Income, Below Long-Term Average

October 26, 2014 by U.S. EIA: Today in Energy

Consumer Energy Costs

Total U.S. household energy consumption expenditures have generally declined relative to disposable income since 1960, although during periods of high energy prices, consumers devote increasing shares of their income to energy. Energy expenditures ranged between 4% and 8% of disposable income since 1960.[read more]

California Home Electricity Rates

California is talking seriously about changing the way utilities price electricity for residential customers. As a result of recent legislative actions, the CPUC now has some flexibility to modify the extreme increasing-block pricing schedules that were adopted after California’s 2000-01 electricity crisis.[read more]

India's coal bubble is perilously close to bursting. This week the Indian court system handed down three landmark energy rulings. While an ultimate decision still looms, the combined weight of these initial rulings reaffirms one thing -- it's time to diversify away from coal.[read more]

National Lab Shows RPS Pays Off at Low Cost

June 16, 2014 by Tom Plant

Renewable Portfolio Standards and Costs

Renewable Portfolio Standards (RPS) have been tremendously successful in driving both renewable energy investment and deployment of renewable resources in the U.S. Two-thirds of all non-hydro renewable capacity additions since 1998 have happened in states with RPS policies.[read more]

Why Biofuels Tend to be Costly

March 14, 2014 by Robert Rapier

Photosynthesis is a very inefficient process. Solar energy is converted into biomass at a rate of only 1 percent or so, which is a fraction of the energy conversion that can be achieved with a solar panel. An advantage of photosynthesis is the biomass that is produced is built-in energy storage.[read more]

The Polar Vortex Wreaks Havoc On Utility Bills

January 31, 2014 by Veronique Bugnion

Polar Vortex and Home Energy Cost

2014 brought the polar vortex to our vocabulary, and with the continuing bitter cold in the Eastern half of the US, most of us are wondering: what’s going to happen to our utility bills? The short answer is that it’s not going to be pleasant in the near term, and probably not in the longer term either.[read more]

High Renewable Energy Costs Damage the Vermont Economy

For those who already think natural gas will win out over renewable power, a judge has said, not so fast. In what may be the first time a U.S. solar power project has been declared cost-competitive against natural gas in a competitive bidding process, a judge has said solar is cheaper than natural gas.[read more]

Electric Cars

One of the nice things about not blogging over the holiday period has been the chance to catch up on other blogs. Llyod Atler’s December pieces in particular have been fascinating, including an invitation to discuss the question ‘Are electric cars going to make it harder to fix our cities?‘[read more]

Home Efficiency and Thermal Imaging

What if you could determine how much heat your home is losing, how much it’s costing you in higher energy bills and what insulation and other improvements would fix it? Oh, and you could accomplish without an energy audit, free-of-charge and from a mobile device no less?[read more]

What’s Ahead? Lower Oil Prices, Despite Higher Extraction Cost

November 18, 2013 by Gail Tverberg

Future Energy Prices

Nearly everyone believes that oil prices will trend higher and higher, allowing increasing amounts of oil to be extracted. This belief is based on the observation that the cost of extraction is trending higher and higher. If we are to continue to have oil, we will need to pay the ever-higher cost of extraction.[read more]

Time to Look Hard at PV Soft Costs

Solar Energy Costs Drop

A kWh is a different product depending on when and where it is delivered. The rapid fall in the costs of solar PV implies that building grids, storage and commercial arrangements able to match supply and demand is much more urgent. This will require strong policy drivers.[read more]
