Renewable Energy RD & D Priorities

the long version

Research, development and demonstration (RD & D) investment in renewable energy technologies has declined over the past 18 years. At the same time, market deployment funding has increased, but the market share of renewables has decreased. Energy supply from technologies that were close to being competitive in the early 70s, such as hydropower, biomass combustion and geothermal, has not subsequently grown at the same rate as the total primary energy supply. & nbsp; Wind power, several forms of advanced bioenergy and to a certain extent photovoltaics, have made it through the RD & D pipeline to market.
