Renewables briefly covered 78 percent of German electricity. On July 25, Germany surpassed the old record of 74 percent renewable electricity.

Renewables briefly covered 78 percent of German electricity

But perhaps the most interesting aspect is power trading between France and Germany on that day. Craig Morris explains. At the end of July, the storm Zeljko passed over northern Europe, causing considerable wind damage and flooding in some areas. Here in southern Germany, however, it was a relatively sunny day. In the north, where it was windy, Germany has most of its wind turbines installed. At the end of week 30, there was a rare combination of a lot of solar and wind power simultaneously in Germany.

The chart above visualizes the situation well, but we still need to include biomass (4.85 GW) and hydropower (2.4 GW). The figures are still preliminary, however. We don’t need to look far for a very low share of renewables, however. A view of week 30 shows that hard coal adjusts the most to fluctuating demand, followed by lignite. France exports electricity when demand is low. Le lycée Kyoto de Poitiers. L'Irlande a économisé 35 millions d'euros et créé 4.000 emplois grâce aux énergies renouvelables. Plus de 27 000 € par foyer pour les renouvelables en Allemagne. Promue en Allemagne comme un doux rêve, l’énergie renouvelable semble destinée à devenir un cauchemar financier.

Energies renouvelables : la Chine reste le premier investisseur mondial. Le Pnue et Renewable energy policy network for the 21st century (Ren21) ont publié conjointement le 11 juin leur bilan 2011 des énergies renouvelables (EnR) dans le monde.

In December leaders from around the world will meet in Copenhagen to try to agree on cutting back greenhouse gas emissions for decades to come.

A Plan to Power 100 Percent of the Planet with Renewables

The most effective step to implement that goal would be a massive shift away from fossil fuels to clean, renewable energy sources. If leaders can have confidence that such a transformation is possible, they might commit to an historic agreement. We think they can. A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world’s energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030.

PRESS RELEASE: Potential of Renewable Energy Outlined in Report by the Intergovernmental Panel on Climate Change — SRREN. PDF Version Abu Dhabi, 9 May 2011 – Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows.

PRESS RELEASE: Potential of Renewable Energy Outlined in Report by the Intergovernmental Panel on Climate Change — SRREN

The findings, from over 120 researchers working with the Intergovernmental Panel on Climate Change (IPCC), also indicate that the rising penetration of renewable energies could lead to cumulative greenhouse gas savings equivalent to 220 to 560 Gigatonnes of carbon dioxide (GtC02eq) between 2010 and 2050. The upper end of the scenarios assessed, representing a cut of around a third in greenhouse gas emissions from business-as-usual projections, could assist in keeping concentrations of greenhouse gases at 450 parts per million. This could contribute towards a goal of holding the increase in global temperature below 2 degrees Celsius – an aim recognized in the United Nations Climate Convention's Cancun Agreements.
