Thus the key deployment factor remains the cost of wind power relative to other energy sources. In the medium term the deployment of wind power will therefore continue to depend on various forms of subsidies. Current market penetration is largely driven by government initiatives rather than market conditions. Deployment will only be increased if technology improvements deliver the large cost reductions and performance improvements that are widely believed to be possible. Should these improvements come about, PV is poised to become a major supplier of energy during the next century.
Biomass energy constitutes a very large potential resource.
The technologies to exploit this resource in IEA Member countries range from being available and in use to being at the laboratory stage. The consequent lack of markets results in limited scope for demonstration projects and further technology development. In order to increase deployment, further work is required on the full range of processes and technologies involved in energy production from biomass. This technology is well developed and has penetrated its existing market to a considerable degree. Various methods for controlling or removing pollutants from pulverised fuel combustion systems have been commercialised and have diffused significantly through the electricity sector.
