20% d'énergies renouvelables en 2020, l'Europe tiendra t-elle le cap ?

Le mercredi 5 janvier dernier, l’European Renewable Energy Council (EREC) a communiqué son analyse concernant les plans d’actions nationaux établis par les États-membres pour répondre aux objectifs de l’Union européenne (UE) en matière d’énergies renouvelables (EnR). Il en ressort que les exigences de 20% de renouvelables dans la consommation énergétique en 2020 seront dépassées.
En effet, les différents plans d’action nationaux conduiraient à ce que 20,7% de l’énergie finale de l’UE soient d’origine renouvelable dans 10 ans. C’est sur l’électricité que comptent le plus les États européens : ils se sont engagés à ce que les EnR atteignent 34% des consommations électriques de l’UE !

Wind power generated 47% of the renewable power, small hydro-electric 20%, geothermal 22%, solar 1%

Achieving a major clean-air goal ahead of state targets, the DWP generated 20 percent of its power in 2010 through wind, water, solar and geothermal systems, city officials announced Thursday.
"This is a big deal," Mayor Antonio Villaraigosa said at a City Hall news conference with environmental leaders. "When we set this goal in 2005, the DWP was the dirtiest utility in the nation. Today, it's the cleanest and we have been able to do it at a cost lower than any other utility in California."
In 2005, the Department of Water and Power generated roughly 5 percent of its energy from renewable sources. Last year, however, that surged to a high of 28 percent for a short time.
"When I set the goal in 2005, no one thought it could be done," Villaraigosa said. "The state had a goal of 20 percent by 2015. We were able to achieve that this year."
The key to achieving the goal, officials said, was the development of the Pine Tree Wind Farm in Mojave and the purchase of the Milford Wind Farm in Utah

Geothermal Numbers fall in Manitoba

Geothermal energy systems are still new to the province, but already Manitoba Hydro statistics show that installation numbers for the technology fell last year.
According to Manitoba Hydro, 551 residential geothermal systems were installed in 2009-2010. Compared to the 756 in 2008-2009 and 721 in 2007-2008, this is a sharp drop.
Despite the numbers, Manitoba Hydro representative, Glenn Schneider remains positive. "It's really a year and a half, two years ago now," Schneider said of the numbers. "We don't have the numbers for the year that just passed."
Schneider pointed out the fact that 2009-2010 saw a huge economic shift. "A year ago we were facing a huge economic crisis," he said. Schneider said because of the crisis, people were very cautious about investing their money, and the geothermal systems are still expensive.

How does solar power work

It is a known fact that the amount of energy that reaches earth everyday in the form of sunlight is enough to supply the entire planet with all the electricity it needs and more than just one time around at that. Now, to turn the energy contained in sunlight to usable electrical energy, a semiconductor is required which is capable of transforming the sun’ rays to electricity when sunlight hits it. Such a device is known as a solar panel or a photovoltaic cell. The oldest and the first photovoltaic cells were made of silicon, one of the most common elements that are found on our planet. The capability of silicon to convert light energy into electrical energy had made it an important discovery, but it is also quite expensive to use this element for capturing solar power.

Report examines environmental impact of new transmission line

The Minnesota Department of Commerce, Office of Energy Security (OES) has released the Final Environmental Impact Statement (FEIS) for the Fargo-to-St. Cloud 345-kilovolt transmission line and substation project.
The intent of the environmental review process is to inform the public, the applicants and decision-makers about potential impacts and possible mitigations for a proposed project.
The FEIS for the transmission project, which passes through part of Douglas County, evaluated impacts for a number of route alternatives, including one along Interstate Highway 94.
It addresses the unique issues that could arise when placing a high voltage transmission line along a major trunk highway. It also presents a comparative analysis of human and environmental impacts amongst route alternatives.
