Solar energy (photovoltaics, PV) is no longer that cute but hardly relevant technology of energy supply – it will evolve into the basis of our entire energy system. The world will have to take another look on PV: adapt itself … Read more
In many discussions on sustainable energy, energy storage is a controversial issue. Particularly non-experts use the lack of simple storage technologies as an unanswerable remark: all nice and well, sustainable energy, but as long as a day without sunshine leaves … Read more
Two factors are underrated again and again in energy policy: the potential of better energy efficiency (check here) and that of renewable energy. In our first column, we saw that important forecasters overestimate demand growth. We foresee global energy growth … Read more
Cleantech might have a much better impact on the economy than just sustainable energy. In the large body of literature that investigates the economic effects of climate policy, most economists are on the pessimistic side; they assume that climate policy … Read more
Energy efficiency is our cheapest energy source, with a very large potential. It has been so for forty years and will probably continue to be so for decades to come. And yet, 99% of energy policy and energy debate is … Read more
Would there still be safe havens if the sea level starts rising as a result of the greenhouse effect? For the time being, people will be relatively safe in industrialised countries. Even in low-lying countries like the Netherlands, that will … Read more
They had come to Amsterdam by the dozens, to the Wind Energy Debate, to let themselves be heard. Opponents of wind energy. Their numbers and particularly their zest testified to it that the debate on wind energy has not calmed … Read more
Of course, a sustainable energy supply will depend primarily on the use of sustainable energy sources. But their intermittent availability requires major changes in the electrical grid. At all levels in the grid, from the individual household to the national … Read more
Some communities declare themselves ‘shale gas free’. Pure symbolism. They know very well that they do not have a say in this. Apparently, they have the (naïve) idea that such a declaration will prevent environmental problems from shale gas recovery, … Read more
Our planet’s temperature rises. There is ample proof for that. CO2 emissions are the main reason, we know that for sure as well. We cannot deny that our wealth and craving for energy have caused this. But we can hardly … Read more
Over the past ten years, we witnessed a very unbalanced development in the global solar cells sector. China rapidly expanded its production capacity, and could therefore use the latest technology and reap economies of scale. But in the end, this … Read more
We are at a turning point in the energy transition, particularly as to the contribution of solar power, says Wim Sinke. So far, the instrument for opening up markets was policy, but it has now become price. Solar panels have … Read more
“Cheap batteries will revolutionise the renewable energy market,” wrote ex-Secretary of State for the UK Chris Huhne past Sunday in the Guardian. For the supply of renewable energy it’s usually not stocks but flows that get the attention. For lack … Read more
