Why we should promote solar water heaters more

France is promoting via aggressive feed-in tariffs the expansion of solar photovoltaic. I believe this is quite a good thing even if our electricity is 90 percent low carbon. (80 percent nuclear and ten percent hydro) Indeed, we will soon need additional capacity for both heat pumps and electric vehicles. However I believe the French (and other) […]

A 13 GW project of wind and solar for India

This week was unveiled what is perhaps to date the largest renewable energies project in the world. Indeed, an Indian company – Airvoice Group – plans to build 10 GW of  solar PV capacity and three GW of wind power. All these capacities are due to be built on various sites within the decade in

A look at the carbon emissions of electricity

I believe fossil fuels will be replaced sooner or later by electricity. This might prove to be a good thing as heat pumps and electric vehicles are two excellent energy efficient solutions. Thus, electric consumption is rising and is due to keep rising in the next decades. Having low carbon sources to generate electricity is very

A huge solar and wind energy deal for Ontario

Solar and wind energies are going slowly but irresistibly mainstream as more and more large deals are being signed worldwide. Even if they still represent a tiny fraction of the world electricity generation, this will change this decade. The 2.5 GW deal signed in Ontario (Canada) by Samsung for $6.6 billion – 4.7 billion euros –

The triple crisis : why we need green jobs

I believe we are beginning this decade with a triple crisis as our economies are crumbling, our climate is warming and our energy supplies are getting scarcer. This assessment of our situation seems pessimistic but it couldn’t be more accurate as it is based on the +700 articles I published here over the past three years.

An offshore wind energy boom in Europe

The European Wind Energy Association (EWEA) published its annual report and the results are encouraging as the offshore wind energy capacity grew by 54 percent in 2009 with 577 MW. The United Kingdom appears to be leading the sector as it installed more than half of the added capacity of the European Union. And this

Germany to cut its emissions by 40 percent

To Reuters, ” Germany will stick to a more ambitious goal of cutting greenhouse gas emissions by 40 percent by 2020 even though the U.N. climate conference in Copenhagen fell short of expectations, a government adviser said on Monday. “ Details of how the country will achieve such drastic cuts still remain to be defined.

Solar energy, a panacea for Africa

Solar energy is to me the panacea for Africa, a continent where 550 million people still lack electricity. With molten salts, concentrating solar could bring light to these populations during important parts of the night. Solar cookers could also help fighting deforestation by removing the need for fuelwood. Now an experiment run in Benin (West Africa) shows
