Criteria for any new technology

Does it work?

Is it affordable?

What is the benefit ?

Spain Hits 50% Wind EnergyNew wind power record: 53.7% of Spains total

electricity demand09 de noviembre de 2009

Wind power in Spain reached a new record last night,providing at its peak 53.7% of Spains total electricitydemand 10.7% greater than the previous record set inNovember last year.

Spanish electricity grid, Red Eléctrica, said that todaysrecord is a first since it was sustained over several hoursduring last night. Between 03.00 and 08.30 on 8November wind met over 50% of electricity demand.

The surge in wind power last night triggered waterpumping stations which transport water into reservoirs.This store of water will then be released over the daygenerating electricity via water turbines at times of peakdemand.

The issue is cost

Typical electric power generation in the UK is

850kWhr/kWp For a £4300/kWp PV system installed plus 5%maintenance for 20 years give an electricity cost of 26.5p/kWhr vs 13p ( retail price)

42 year payback time on avoided electricity cost.

In a survey of architects by Romag Ltd 100% of respondents cited cost as the main barrier to use of PV.
