Wind Energy Planning
Renewable energy is essential to modern society – reducing harmful emissions from fossil fuels and making us more self sufficient. This site will explore what people are doing to help get us closer to a greener, renewable energy sourced world Read more »
What is Stopping the Severn Barrage?
The idea of an electricity generating tidal barrage across the Severn Estuary between England and Wales has been around for 160 years. Conceptually the Severn tidal barrage is a simple and green renewable energy technology in a location which has the second highest tidal range in the world (next to the bay of Fundy in Canada).
The Severn Barrage has had numerous advocates from James Lovelock and Tony Blair to the Welsh Assembly. Why is it then that every time the idea is resurrected by a new advocate it rapidly disappears from the headlines to sink back into the mudflats?

Marine renewable energy technologies are young but show much promise for the future. Although unlikely to be as commercially successful as wind energy in the short term, the profile of wave and tidal energy is likely to be much greater over the next few years.
The Carbon Trust told us several years ago that 20% of UK’s current electricity demands could be met by wave and tidal energy. The Ocean Renewable Energy Coalition says 252 million megawatt hours a year could be generated off the coast of the US and the World Energy Council has said 1 million gigawatt hours of wave energy hits Australian shores annually.

Salazar Holds First Offshore Energy Public Meeting
Secretary Salazar believes that US offshore wind energy resources could lead America’s Clean Energy Revolution. Today he held the first of a series of public meetings to consult on a new offshore energy plan.
At a previous meeting with 25x’25 America’s Energy Future – a group seeking to reduce America’s carbon emissions – he said “More than three-fourths of the nation’s electricity demand comes from coastal states and the wind potential off the coasts of the lower 48 states actually exceeds our entire US electricity demand“.

5 tidal barrage and lagoon projects for the UK Severn Estuary were chosen for a government shortlist today.
The huge 10 mile long Cardiff Weston Barrage proposal from Weston Super Mare to Cardiff could generate as much as 5% of UK electricity requirements, whereas the smaller Bridgwater Bay Lagoon project between Hinkley Point and Weston Super Mare has the potential to generate just under 1%.
