Solar Energy
Solar Energy (Britannica Online) radiation from the Sun capable of producing heat, causing
chemical reactions, or generating electricity. () the total
amount ofsolar energy incident on Earth is vastly in excess
of the worlds current and anticipated energy requirements.
If suitably harnessed, this highly diffused source has thepotential to satisfy all future energy needs. In the 21st
century solar energy is expected to become increasingly
attractive as an energy source because of its inexhaustible
supply and its nonpolluting character, in stark contrast to the
finite fossil fuelscoal, petroleum, and natural gas.

Solar Energy
Solar Energy (Wikipedia) Solar energy is the radiant light and heat from the Sun
that has been harnessed by humans since ancient times using
a range of ever-evolving technologies. Solar radiation along
with secondary solar resources such as wind and
wave power, hydroelectricity and biomass account for mostof the available renewable energy on Earth. Only a minuscule
fraction of the available solar energy is used. (wikipedia)

The energy system challenges
Global warming, climate change Resource depletion Need for a deep change of the energy system
Based mainly on renewable, rather than exhaustible sources Decentralized, generation close to consumption Efficient (cogeneration) Fair
Transition will not be easy STP can play a major role in this context

3000 km
90 % of the total electricitydemand could be suppliedfrom STP plants covering
300x300 km2.
Effcient transmission viaHVDC would allow electricity
supply to remote areas withmoderate losses.
