Cheap energy storage speeds up
Costs of producing renewable energy keep coming down; and technologies for cheap energy storage keep evolving. Therefore, the eternal problems with solar and wind energy appear to be more and more outdated (‘what to do if the sun doesn’t shine and the wind doesn’t blow’). In the past, we already devoted our attention to this
Renewables versus nuclear – a choice already made
The most important low-carbon energy sources, renewables and nuclear, compete for investment funds. But if we are not mistaken, the dice have already been thrown in this contest of renewables versus nuclear. Renewables have won. Although it might still take a decade or more for parties involved to agree on that. In two articles, we
Energy policy: don’t just choose low-carbon – create a new energy system
A recent article in Nature Energy confirms what we might have surmised already: renewable sources are much better at creating a low-carbon energy future than nuclear power. They do need quite another electricity infrastructure. But grid companies quickly learn how to change their energy policy, and create a new system that fits well these new
The solutions are here!
The solutions are here!, talking about major global problems. Solutions that exist already but are not generally applied. Or that are under severe and undeserved attack and therefore receive insufficient support. We have in mind: renewable energy and energy storage, food for 10 billion people, cleaning up all plastic waste and preventing new waste to
New technology for drinking-water production
Researchers at Monash University in Melbourne, Australia, have developed a new technology for drinking-water production. They use metal-organic frameworks (MOFs) that remove ions dissolved in salt or brackish water, producing potable water. The MOFs can be regenerated quickly, under the influence of sunlight. Therefore, this results in a scheme of producing drinking-water from salt water
Energy autarky more difficult than expected
The Dutch Wadden islands aimed to attain energy autarky in 2020. They fail to reach that target. For in order to do this, energy production and consumption don’t just need to match over a year; they also need to match continually, whereas both production and consumption vary considerably over time. That is difficult to achieve.
EASAC: burning biomass often doesn’t reduce CO2 emissions
The European Academies’ Science Advisory Council (EASAC) urges the European Commission to base its carbon accounting on science and the real effects on climate. The present accounting rules favour energy from biomass. Whereas often, burning biomass doesn’t lower CO2 emissions at all. EASAC suggests a standard based on real emission reductions within 10 years. This
Fast and slow revolutions
In Europe, most people seem to have lost their belief in improvement. A concept of dreamers. But improvement takes place all the time; and the odd thing about this is that many improvements are swift and fundamental in nature, but are never highlighted as such. A story of fast and slow revolutions. Fast and slow
