A new study concludes that it would be technically and economically feasible for New York State to meet all of its energy needs from renewable sources by 2030, but researchers say the transition would involve building wind, solar, and other alternative energy sources on a mass scale. (more…)

We hear a lot about grid parity, don’t we? That’s the point at which the cost of energy generated by solar, wind, and other renewables is the same as that generated from conventional sources. The author of this article on Sharp Electronics new 43.5%-efficient solar cell writes: “Sharp shattered the efficiency record with its concentrator triple-junction compound solar cell, (more…)

On January 24, the California Public Utitlies Commission will vote on an important precedent for using renewables to enhance grid reliability.

Grid reliability requires that there be a certain amount of local generation–known in wonkspeak as ‘local capacity requirements’, or LCR. (more…)

In a recently released report, the Annual Energy Outlook 2013 (AEO2013), the US Energy Information Administration (EIA) projected the US energy markets through 2040. Their projections only take into account the effects of policies that have already been implemented in law or final regulations. The EIA found that the growth in energy production has (more…)

There is more urgency to combat climate change than before, but how are the big economies – China, the US, India – getting on together? Each country has its own agenda and is experiencing its own growing pains of one kind or another.

How does a country emit such massive quantities of carbon in the first place? (more…)

Here’s an article that points to a controversy about smart grid, i.e., about the concept of two-way communication between the electric generation plant and the customer, and the application of intelligence to flow of information. Apparently, someone is alleging that the money spent in the arena has been misspent, that smart grid won’t improve grid reliability, etc. (more…)

In October 2011, the Japanese Cabinet—still reeling from the Fukushima reactor meltdown earlier that year—approved an energy white paper calling for reduced reliance on nuclear power and increased emphasis on renewables.

A little over a year after the approval of that policy, I wondered to myself if Japan was sticking to its goals, or if—with the immediate shock of the Fukushima (more…)

The Los Angeles City Council recently approved a contract with a 250 MW PV plant. It’s on tribal land, and according to this article, the tribe is pleased with the economics of the deal.

Ratepayers should also be pleased. This contract adds 2.9% renewables to LADWPs mix, and at a price of 9.1 cents/kWh. Read the details, here (pdf). (more…)

Here is some really good news coming from the European Union. From the EU environmental agency – EEA, located in Copenhagen – greenhouse gases emissions from the 15 first Member States decreased by 3.5 % between 2010 and 2011. The EU-15 emissions are now 14.1 % below the base-year level under the Kyoto Protocol. (more…)

Energy books tend to be either jargon-filled tomes or hand-wringing, end-of-the-world, please-just-shoot-me-now reprimands. So it was a relief to see that Brian Keane avoids both of these worn-out roads in his new book, “Green is Good: Save Money, Make Money, and Help Your Community Profit from Clean Energy.” (more…)
