A joint working paper from the International Renewable Energy Agency (IRENA) and the Copenhagen Centre on Energy Efficiency (C2E2) illuminates crucial synergies that can help to ensure a sustainable global energy future. The interplay between energy efficiency improvements and the deployment of renewable energy technologies is complex.

The vision of the scheme is established India as a global leader in Geo-thermal power by deployment of Geo-thermal energy capacity of 1000 MWth in the initial phase till 2022. The scheme is to focus on assess the potential of geothermal resources in the country and promoting RDD&D projects of Power production and Geo-exchange Pumps.

The technology roadmap for Geothermal Heat and Power offers a strategic plan to maximise deployment of these energy resources by 2050. It projects that 1 400 TWh of electricity per year could come from geothermal power by 2050, up from 67 TWh at present. Additionally, geothermal heat (not including ground-source heat pump technology) could contribute 5.8 EJ (1600 TWh) annually by 2050.

Buildings account for almost a third of final energy consumption globally and are an equally important source of CO2 emissions. Currently, both space heating and cooling as well as hot water are estimated to account for roughly half of global energy consumption in buildings.

In recent years, renewable energy has increasingly attracted public and policy attention particularly for its potential to contribute to
reductions in GHG emissions. Most interest has focused on the use of renewables in power generation and as biofuels.

The use of heat pumps in connection with solar thermal energy systems is becoming increasingly popular in Central Europe. Other countries are also finding this combination attractive.
