Louisiana’s Public Service Commission (PSC) will vote this Wednesday, April 17th on whether to preserve or dismantle net metering in the state. The vote will answer the central question in the net metering docket (LPSC Docket number: R-31417) – how valuable is the solar energy produced from net-metered solar systems? (more…)

Portugal generated more than 70 percent of its electricity from renewable sources of energy during the first quarter of 2013, a record amount fueled largely by hydroelectric and wind energy sources, according to a report from the country’s grid operator.

Hydroelectric generation provided 37 percent of the (more…)

The combustion of fossil fuels are a huge health hazard as to a recent United Nations report, 3.3 million people died from outdoor air pollution in 2010. An additional 3.5 million people die early annually from indoor air pollution.

I had noted in a previous Cleantechies article that air (more…)

Anyone who discounts what Bill Gates says on any issue has some explaining to do. Recall that, when he ran Microsoft, Gates would famously make himself available to talk with employees who wished to present their ideas, but was aggressively unforgiving of people who hadn’t done their homework, and were unable to support their positions in reasoned (more…)

NV Energy unveiled its new NVision Plan last week, a policy initiative that proposes shutting down coal plants and investing in new renewable energy and natural gas generation. On the surface, that sounds great – shuttering coal plants, reducing carbon emissions, increasing investment in renewable energy and creating jobs. All good things, right? (more…)

When I got started in this subject a few years ago, the efficiency of thin film solar (i.e., the percentage of sun’s radiant power that is converted into electricity) was measured in single digits. Here, we just achieved 16.1%, a huge increase from the former record holder at 14.7%. (more…)

The so-called “artificial leaf,” a solar cell being developed by MIT and Harvard scientists to produce low-cost electricity, is now capable of “self healing” the damage that occurs during energy production, clearing a hurdle to deploying the device in the developing world, scientists say. (more…)

Just a week after Governor Cuomo announced the first round of awards under the NY-Sun Competitive PV program, the Governor is back at it announcing that $13.5 million will be made available to help reduce the overall cost of installing solar, specifically non-module costs. The combination of these announcements represents a one-two punch for (more…)

Algae biofuel is an alternative to fossil fuel that uses algae as its source. Several companies and government agencies are funding efforts to reduce capital and operating costs and make algae fuel production commercially viable. Taking an approach similar to that used for discovering new therapeutic drugs, chemists at the University of California, Davis, have (more…)

A wind farm being planned in a remote Alaska village will seek to demonstrate that small, vertical-axis turbines can produce more energy than conventional wind turbines and cause less environmental damage.

While the turbines used in most standard wind farm projects can produce turbulence that actually (more…)
