Marine hydropower could make waves in renewable energy, if it can overcome technological and financial challenges. Chris Bentley takes a look.
Portugal produced more power from clean energy sources in March than it actually needed, marking the first time in the 21st century that renewables have topped 100% of its production. But a dearth of energy connections with the rest of Europe remains problematic, explains Sam Morgan.
There are many steps we can take to deal with the flexibility of renewable energy: better storage, smart meters, lowering demand via efficiency. But what about getting wind to help balance out the grid in Europe? John Timmer of ArsTechnica looks at harnessing weather patterns for the energy transition.
After power producer Iberdrola announced the closure of their last coal plants, the Spanish government has said it might intervene to keep them open. Such an intervention, write energy experts Gerard Wynn and Paolo Coghe, is taking a page out of Donald Trump’s book. It is costly, bad for the investment climate, and for the planet’s climate.
There are signs that the diesel scandal is starting to turn customers away from the technology. A list of sales by manufacturer reveals the reliance of German carmakers on diesel. Craig Morris investigates.
In April 2016, Portugal’s electricity generation came almost entirely from renewable energies (95,5%) and ran in early May on RES generation exclusively for 107 hours straight. A transition to 100% renewable energies is thus closer than ever in the country. Rita Antunes and Francisco Ferreira from ZERO – Association for the Sustainability of the Earth System explain.
Despite the fact that in the sunniest region of Europe there is a vast potential of energy from the sun (and wind), renewable energy is a resource that is being ignored. In a time when Southern European countries are struggling with debt and stagnating economies, clean renewable energy solutions can be a smart way to go. Expert studies commissioned by Greenpeace Croatia, Greece, Italy and Spain show how the Southern European governments can boost their economies, reduce greenhouse gas emissions and accelerate their energy transition by enabling massive small-scale investments into renewable energy and energy-efficient solutions. Dejan Savic summarizes the findings.
While the world celebrates unprecedented renewable capacity additions, there are clear signs that this growth stops for wind and solar at a small share of the market. Italy and Spain are perfect examples for this, explains Craig Morris.
In recent years, the increasing competitiveness of wind and solar power has been widely hailed. But there is a cloud to this silver lining – power production does not match power demand. As a result, the actual value of wind and solar power will decrease as we get more of it. Craig Morris says policymakers should pay attention.
And then there were three… E.ON, one of Germany’s Big Four utilities, is selling its conventional power plant fleet. Is this a special case, or is E.ON setting an example for the other utilities? Craig Morris investigates.
