50% more electricity has been generated by renewables such as hydro, wind, solar and other sources than in the same period last year and now generates nearly 10% of all electricity in the UK.
There is other good news in the latest quarterly energy figures at least in terms of carbon emissions:
electricity consumption was 1½% lower than in the second quarter of 2010
fossil fuel dependency was at a record low of 85.7 %
the supply from coal in the second quarter of 2011 fell 2.3%, gas decreased by 18.3% and nuclear rose by 38.3%
in the second quarter of 2011 renewables accounted for 9.6% of electricity supplied, whilst nuclear supply exceeded 20% for the first time since the second quarter of 2006
the total electricity supplied by all generators in the second quarter of 2011 was 1.7% lower than a year earlier
final consumption of electricity for domestic use decreased by 3.7%.
This will all have the positive consequence of having reduced overall carbon emissions in the last year.
But prices have been rising. Average industrial gas prices, including the Climate Change Levy (CCL), were 34.1% higher in current terms in Q2 2011 compared to Q2 2010, whilst prices excluding CCL were 35.4% higher.
Wholesale gas prices are expected to continue to rise, with forward market prices trading at 76p/therm in 2016.
The truth is that fossil fuel price volatility has been, and is expected to continue to be, a bigger driver of energy price variations than the impact of energy and climate change policies.
