Number of the week – 90

Dave Timms writes in the Guardian about the installation of solar systems in Bangladesh:

 Late last year, the award-winning renewable energy scheme Grameen Shakti celebrated the installation of its 1 millionth home solar energy system – and that in one of the world’s poorest countries. That’s one every 90 seconds.

 Timms also praises the solar installations in the US:

This year, the US is on track to install one solar energy system every four minutes. Not bad you might think, especially in a country where powerful oil and gas interests are keen to block progress on clean energy.
