Germany’s utopian dream of transforming itself into the world’s green powerhouse is collapsing as its political and media establishment is mugged by reality. The country’s climate obsession has turned into one of the country’s biggest political and economic handicaps, making Germany almost ungovernable.
The hidden consequences of a massive use of intermittent renewable energy systems for electricity production are highlighted, using existing electricity production data from Germany from the last 5 years, where presently a system is in operation with an installed capacity of about 50 GW in wind turbines (sum of onshore and offshore wind) and 40GW in photovoltaic panels.This fleet of intermittent renewable systems produces more than half of the yearly renewable electrical energy of Germany, the rest being produced by hydro, so-called ‘biomass’ and a very small fraction of geothermal sources
Global energy investment fell by 12% in 2016, the second consecutive year of decline, as increased spending on energy efficiency and electricity networks was more than offset by a continued drop in upstream oil and gas spending, according to the International Energy Agency’s annual World Energy Investmentreport.
Global energy investment amounted to USD 1.7 trillion in 2016, or 2.2% of global GDP. For the first time, spending on the electricity sector around the world exceeded the combined spending on oil, gas and coal supply. The share of clean-energy spending reached 43% of total supply investment, a record high.
The biggest critics of President Trump’s decision to withdraw from the Paris climate accord are also the world’s biggest hypocrites on energy policy, top environmental groups charged Wednesday in a report that found many top nations’ rhetoric on cutting emissions doesn’t line up with how and where they spend their money.
The key finding: The G-20 nations spend roughly four times as much in public financing for fossil fuels as they do supporting renewable energy sources such as wind and solar. The report examines loans, grants, guarantees, insurance and other types of public finance offered either by the governments, government-owned financial institutions and credit agencies, and multilateral groups made up of G-20 countries.
Hundreds of built and proposed hydroelectric dams may significantly harm life in and around the Amazon by trapping the flow of rich nutrients and modifying the climate from Central America to the Gulf of Mexico. These findings, published in Nature, emerge from a multidisciplinary, international collaboration of researchers from 10 universities, led by scientists at The University of Texas at Austin.
To meet energy needs, economic developers in South America have proposed 428 hydroelectric dams, with 140 currently built or under construction, in the Amazon basin — the largest and most complex network of river channels in the world, which sustains the highest biodiversity on Earth.
The 2017 Edition of the REN21 Renewables Global Status Report reveals a global energy transition well underway, with record new additions of installed renewable energy capacity, rapidly falling costs, and the decoupling of economic growth and energy-related carbon dioxide (CO2) emissions. This year’s report continues REN21’s long-standing tradition of providing the most up-to-date data and informative infographics to detail renewable energy’s contribution to the energy transition.
The electric car has dropped out of favor in the country that pioneered renewable energy.
Sales in Denmark of Electrically Chargeable Vehicles (ECV), which include plug-in hybrids, plunged 60.5 percent in the first quarter of the year, compared with the first three months of 2016, according to latest data from the European Automobile Manufacturers Association (ACEA). That contrasts with an increase of nearly 80 percent in neighboring Sweden and an average rise of 30 percent in the European Union.
Water reservoirs created by damming rivers could have significant impacts on the world’s carbon cycle and climate system that aren’t being accounted for, a new study concludes.
The study, conducted by researchers at the University of Waterloo and the Université libre de Bruxelles, appears in Nature Communications. It found that man-made dam reservoirs trap nearly one-fifth of the organic carbon moving from land to ocean via the world’s rivers.
Un des plus grands parcs éoliens offshore au monde a été mis en service le 8 mai au large des Pays-Bas. Ce parc, baptisé « Gemini », dispose d’une puissance installée de 600 MW et pourrait produire, selon son exploitant, 2,6 TWh par an grâce aux vents « les plus forts et les plus réguliers
Germany’s SolarWorld, once Europe’s biggest solar power equipment group, said on Wednesday it would file for insolvency, overwhelmed by Chinese rivals who had long been a thorn in the side of founder and CEO Frank Asbeck, once known as “the Sun King”.
L ’énergéticien allemand E.ON a annoncé le 11 avril son investissement dans un futur site de démonstration en Irlande où sera testée une éolienne « aéroportée » de la société Ampyx Power. Explications.
