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]

Rationalizing California's Residential Electricity Rates

September 30, 2014 by Severin Borenstein

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]

Uncertainty, Rising Costs Cloud Indian Coal Sector After Landmark Supreme Court Rulings

September 4, 2014 by Justin Guay

India's Coal Sector

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

January 28, 2014 by Willem Post

With regard to renewable energy, it DOES matter what Vermont does, especially if it is on the wrong track to the detriment of Vermont’s economy, which has been in near-zero-growth mode since about 2007, with declining real household incomes since about 2000.[read more]

Natural Gas Loses to Solar Energy on Costs, A First

January 9, 2014 by Lewis Milford

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]

Will Electric Cars Help or Hinder Climate Action?

January 1, 2014 by Lindsay Wilson

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]


Mapping Whole Communities and Their Homes with Thermal Images to Reduce Heat Loss

November 18, 2013 by Jim Pierobon

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

October 1, 2013 by Nigel Morris

I recently wrote about the rising issue of compliance costs in solar installations and added some recent statistics based on my intuition and a few discussions, but it prompted me to conduct a survey to collect some new, more up to date data.[read more]

Solar Deployment: Are There Limits as Costs Come Down?

September 27, 2013 by Adam Whitmore

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]

The Average Price of Electricity, Country by Country

September 25, 2013 by Lindsay Wilson

Worldwide Electricity Costs

Australia and Germany each just had an election. In both cases electricity prices were an election issue. That seems fair enough given that in both countries they are paying significant more $/kWh than most countries. Out of curiosity I thought I’d see who is paying more for their power.[read more]

September 20, 2013 by Silvio Marcacci

Renewable Energy Costs

Renewable energy becoming more cost-competitive with fossil fuels isn’t news – as technology improves and more clean power generation comes online, electricity without emissions gets cheaper. But one new analysis reveals just how shockingly cheap it’s gotten.[read more]
