I had noted last year that cleantech investments had decreased from their peak of  $317.9 billion in 2011 to reach $286.2 billion in 2012. 2013 was an even worse year as total investments reached only $254 billion. To Bloomberg New Energy Finance : ” The reduced volume of investment in 2013 reflected […]

Cleantech investments decreased again in 2013

Solar saw another record year in 2013, with as much around 35 GW of capacity installed according to IHS. China and Japan leaded the world in 2013 with 8.6 and 6.3 GW respectively. This is especially staggering once you know that in 2008 and 2009 yearly installations were below ten […]

The future is solar : 49 GW to be installed ...

Safe and clean nuclear energy seems everyday further away as the horror story of the Fukushima-Daiichi nuclear plant in Japan unfolds. Each passing year seems to bring its flow of bad news. As the New York Times notes : ” Problems at the plant seemed to take a sharp turn […]

The Fukushima horror story goes on

While browsing my RSS feeds, I found on Inhabitat a great idea on how to park dozens of bikes without wasting space in streets. Only eight meters wide and eleven meters deep, a single Eco Cycle parking can store 204 bikes. The Japanese company Giken has installed many of these […]

A great Japanese idea to park bikes

In the wake of the tragic catastrophe and the nuclear incident that shook Japan in 2011, we have seen that the local government is willing to push renewable energy sources forward. Among them, solar energy and wind power. This has led to the installation of 1,12 GW of solar PV […]

A renewable energy boom in Japan

Dutch windmills performing a ballet

According to Bloomberg New Energy Finance, investements in clean technologies fell by 11 percent in 2012 compared to their 2011 levels. They still amounted to 268.7 billion USD or over 200 billion euros. These news aren’t all that bad even if this decrease marks the end of a seeminlgy unstoppable […]

Cleantech investments fell in 2012

Nuclear power no thanks ?

This is the question many are asking themselves as the Japanese government initially wanted to go nuclear free by 2040 but finally removed the specific deadline as the New York Times reported. Nuclear plants can last decades provided they are operated and maintained carefully. Nuclear accounts for 18 percent of […]

Can Japan, and the world, ever be nuclear free ?

Sharp transparent solar panels 2

To Engadget : ” Sharp has announced an unusual photovoltaic panel for the Japanese market that collects energy from the sun while still allowing the light to shine on through.“ ” Though it’s rated at a lowly 6.8 percent efficiency, the glass-like properties make it useful as a construction material […]

Sharp presents transparent solar panels

As Treehugger reported last week, the Japanese company Sharp has broken another record : 43.5 percent of efficiency, to be compared with their previous record, 36.9% efficiency which had been reached in November 2011. Typical solar panels in the market today still have around 15 or 20 percent of efficiciency. […]

Another solar efficiency record : 43.5 %


Are we finally getting things right on climate change ? Not completely, but what happened last week may be a good omen for the Rio +20 conference. As I noted in a post published yesterday on Cleantechies : ” Further to the Camp David meeting last week, G8 leaders agreed […]

G8 leaders agree to act on climate, air pollution

Japan seems to become pretty serious about climate change as it will soon make official a law mandating for 80 percent cuts of greenhouse gases emissions  by 2050 (compared to 1990, just in line with IPCC recommendations) Not totally unrelated to these most commendable goals, the country enacted generous feed-in […]

Japan set ambitious 2050 goals, feed-in tariffs

A year after the catastrophic events in Fukushima, Japan is planning to be nuclear free by May 5. It is I believe a good opportunity to focus on the future of the industry. Opinions diverge on this critical issue. Some believe nuclear is bound to disappear as it has a […]

A year after Fukushima, and the future of nuclear
