Hi , I'm Tom Langdon-Davies from a farm near Exeter in sunny Devon, South West England. I have worked all over the world for energy companies, renewable and conventional. Now it's time for me to see what I can do to raise awareness of the easy things we can do to make our energy more sustainable. Thanks for reading. Please help me by commenting!
After a brief spell seismic surveying around Europe and Africa, I ran the Natural Energy Centre in London - that was back in 1977, and we...

Share of Renewables in Total Generation Looking Good - How can it be Increased Further?
Will we get to 30% for a whole year by 2020, which is the national target?
The seasonal variations in wind and solar PV suggest that what is most needed is more wind power to boost Q4 and Q1 generation, when solar is at its lowest, and wind is statistically higher.Reading from the graph, this would require wind going from around 12% to 18% of generation in those quarters, a 50% increase in wind generation.
You can forget storage as a means of ironing out seasonal variation - a battery large enough to store electricity in sufficient quantity to shift supply for several months would be very big, even more expensive than more nuclear power.
Any ideas on how to shift consumption from winter to summer? More energy efficient homes would help!
