LONDON, England, May 03, 2006 (Refocus Weekly)
Total generation of green power in Britain
increased 250% from 1996 to 2004, from 5,685 to 14,171 GWh.
The increase was led by biofuels, which rose four-fold over the
period to provide 7,302 GWh of the total, according to the latest
data on renewables from the Department of Trade & Industry. Of that
sector, landfill gas rose 570% to 4,004 GWh, while co-firing with
fossil fuels rose to 1,022, municipal solid waste combustion
increased to 971, sewage sludge digestion rose to 379 and other
biofuels increased to 6,122 GWh in 2004.
Large-scale hydro (excluding pumped storage) was the second
technology for output, generating 4,648 GWh for an increase of 140%
over 1996. Small-scale hydro increased 240% to 282 GWh.
Onshore wind rose 360% over the period, from 488 to 1,736 GWh,
including an increase of 140% from 2003 to 2004, while offshore wind
grew from nothing to 199 GWh over the period. Solar PV increased to
4 GWh in 2004.
In terms of installed electrical capacity, biofuels and wastes rose
from 452 GW in 1996 to 1,333 GW in 2004, a three-fold increase,
while large hydro increased to 1,406 and small hydro to 184 GW.
Onshore wind was 809 GW by the end of 2004 while offshore turbines
accounted for 124 GW of capacity, with shoreline wave facilities at
0.5 GW and solar PV at 8.2 GW.
Total installed capacity for green power in the country increased
170% over the period, from 2,271 GW in 1996 yo 3,865 in 2004.
Biofuels provided the highest load factors at 66%, while hydro was
35%, onshore wind was 26.6% and offshore turbines were assessed at
24.2%.
The UK generated 9,986 GWh of green power in 2004 on an Renewables
Obligation basis and 17,693 GWh on a Renewables Directive basis, the
report shows.
For the RO, biofuels accounted for 6,331, while onshore wind was
1,736, refurbished large-scale hydro was 1,434, small-scale hydro
was 282, offshore wind was 199 and solar PV was 4 GWh in that year.
On a Renewables Directive basis, biofuels is rated at 7,302 GWh,
large hydro at 4,648, imports of certified electricity at 3,522,
onshore wind at 1,736, small-scale hydro at 282, offshore wind at
199 and solar PV at 4 GWh.
