Renewable electricity taking off

4.7 Million EV Charging Units Expected Worldwide by 2015:

The first affordable mass-produced electric vehicles will hit the
streets soon. Once the Nissan Leaf begins to make
its way from dealerships to consumers, the electric vehicle charging
revolution will begin. A new report by Pike Research reveals that there
will be an estimated 4.7 million EV charging units in operation
worldwide by 2015. The report indicates
that about two-thirds of EV charging equipment sales will be in the
residential sector, people prefering the convenience of
charging their vehicles at home where it will typically cost consumers
less than £1 to fully charge a vehicle.

Photovoltaics Likely to Reach Milestone of 10 Gigawatts Installed in
2010 - But Wind Remains Far Ahead:

GreenTech Media, June 11, 2010

The threshold of 10 gigawatts of photovoltaic solar installed globally
in a single year is likely to be reached this autumn. Ten years ago, the
total amount of photovoltaics installed in the year 2000 was 170
megawatts. Since then, the solar photovoltaic industry has grown at a
51 percent annual growth rate, and 170 megawatts is now the size of a
healthy utility installation or a small solar factory. Photovoltaic
module pricing has made radical progress, as well, moving from $300 per
watt in 1956, to $50 per watt in the 1970s, to $10 per watt in the
1990s, to $2 per watt today. By comparison, the wind industry installed
27 gigawatts in 2008, 38 gigawatts in 2009 and has a total installed
base of more than 158 gigawatts compared to PV's installed base of about
20 gigawatts. 2010 will see more than 200 gigawatts of installed wind
and the Global Wind Energy Council expects that to double to 400
gigawatts by the end of 2014.

NOTE In UK Solar PV is at present about 85% of the installed capital
cost of offshore wind, this may well come down further in the next year
or so if some current UK PV developments reach the market. BUT wind
offshore has a utilisation of 25 to 30% while Solar PV is 15-17%.
SO Solar PV, above [say] all car park bays, will cause much less visual
and environmental effects than wind energy. Be easier to connect to the
electricity grid. And require less maintenance ?? Electric car charging
points could be provided ??

In a way one needs both: Solar in Summer especially to feed Supermarket
Air Conditioning and Refrigeration: Wind in winter for heating & lighting.
