Reasons to be interested in renewable energy:
• Climate change
• Running our of oil and gas
• Security of supply
Available choices of renewable energy:
• Hydro Power=17% of world electricity
• Nuclear power = 17%
• Other= 1.5% ( not more than 10% at best in future)
Other:
• Wind: Govt target is extremely challenging; need to solve problem of intermittency
• Biomass: promising but difficult to source and needs large subsidy
• Waste incineration: very promising but need to make much more localized
• Wave power: So far unconvincing demonstration
• Solar: has become worthwhile
• Desertech : mirrors around desserts; extremely expensive
• Tidal power could reliably satisfy 10% to 15% of demand in the UK
• Tidal range technology is proven and sound
• The Severn barrage could provide 5% of UK Energy.
• The Severn Barrage could provide 120 years of low carbon electricity, with a predicted installed capacity of 8640 MW compared with 240 MW at La Rance.
• It would be the biggest project of its kind in the world and would put the UK in the forefront of tidal technology
We are going tio have to re build the world in 20 years in order to become a low carbon society. The UK is committed to an 80% reduction in carbon emission by 2050. Over the next 10 years many of the UK’s power generators will be shutting down.
£200 bn of new investment needed over the next 10 years to replace lost capacity and provide future needs.
Diversity is Security.
Nuclear is a huge factor.
Coal and carbon capture: Britain must take the lead but it falling behind.
Gas: we must within three years build more gas storage
Renewables:
• Wind has a part to play but as the only resource is a mistake
• Water in the case of the UK means tidal energy: UK must attract the world to invest in this resource and we must think in terms of a 20’30 year investment cycle
Road map
There is a need for a road map
Severn barrage
Interesting if it’s economic: Need to bear in mind that for the same cost we could build four nuclear power stations quicker
Wind
Technology needs to develop so that a permanent supply can be achieved
Houses
Must be upgraded: Micro generation must be encouraged and we must be more ambitious
Transport
Must be de carbonized by 2050
Heat: lots of potential (solar; ground source): at the moment tending to be enthusiastic rather than focused:
Solid state lighting: very effective and the public sector should adopt it in all public buildings
Public education: need for social scientists; education; psychologists? Very important
Community energy projects: great potential
Marine power technology: Specialist campuses will be established into which seed corn can be invested
Wind power: A plea for more encouragement of this resource: it is a valid and effective resource
Green Investment Bank: Mr Hendry said that he would if in power seek funding to establish such a bank which would provide extra funding and R & D support
Planning: A need for greater flexibility. The Conservatives would establish a Planning Commission which would report to the Home Secretary answerable to the public.
Cost of investment estimated for UK at £200 by 2020: £60 on every annual power bill by 2090
