Investment in the development of technologies to generate heat and solar cooling can be avoided 800 mega tonnes of carbon dioxide emissions (CO2) per year by 2050, equivalent to the total CO2 emissions of Germany in 2009.

IEA roadmap for heat and solar cooling (SHC), which determine the optimal ways to promote technological upgrading heating and cooling with solar energy.

Technologies such as hot water heating technology in the waste almost no greenhouse emissions.

Although solar energy is used to generate heat and cooling is still a small portion of the world's energy needs, but new route IEA stressed if the government and industry have the specific action, Solar could produce more than 16% of the total energy used to produce low-temperature and 17% of the total energy used to cool the globe. To achieve this goal, the world must increase 25 times the level of technology deployment SHC over the next four decades.

Global energy demand for heating heat generation accounts for about 50% of the end-use of energy worldwide, more than all global energy needs for electricity and transport.

Using solar energy to heat an important contribution to helping solve the second challenge is climate change and energy security.

In addition to directly replace fossil fuel heating to heat, the heat generated by technology solar energy can replace electricity to heat water as well as heating the building.

Technologies from temperature cooled solar energy can reduce the burden on the national electricity grid through the replacement of all or part of the air conditioning system powered by electricity in the building.

Roadmap for development of solar energy is expanding the use of this technology in the industry. The process industry promises huge potential for technology heating heat generated by solar energy. These technologies can meet 20% of the total global industrial energy demand for heating low temperature 2050.

However, the IEA stressed the need to support the development of solar energy in the specific policy and practice.

The need to create stable long-term policy framework to develop the technology to create heat and cooled by solar energy, economic incentives, removal of obstacles, such as lack of quality control standards funding and mechanisms to support research, development and deployment of promising technologies in the early stages can achieve high-scale commercial production within 10 years.

Sponsoring organizations in the developing countries should also accelerate the deployment of SHC technology is mature and highly competitive.
