The UK has outstanding possibilities of contributing to climate change (CC)
through wind renewable energy technology (RET). Further development is expected from
geothermal source heat pumps (GSHP), biomass, hydroelectric and passive solar design`RETs. The UK has a limited quantity of resource for solar power. Hydrogen RET
possibilities are still unknown.
Ashton Green (AG) and London are examples of rural and urban developments
respectively renewable energy (RE) developments. Both approaches depend on the availability of resources in-site. AG approach bears the economics more than London, which targets to be in the vanguard of RETs development.
Technology has evolved significantly since AG project was started. This can lead to
a review of the technologies to be implemented. London, on its side, may consider the possibility of settling an Energy Service Company (ESCO) to serve the city as energy service provider.
