The Abundance of Solar Energy

The sun is the source of all forms of energy on all planets in the solar system. Energy from the (depleting) fossil fuels, from (renewable) biomass, wind, oceans, hydro and even geo-thermal sources are at the disposal of humankind, since the Earth was spun-off by the Sun with all its inner and outer energy sources. The sun radiates about 10'000 times the energy we presently need on Earth, some of it being reflected back into space, a lot being absorbed by water surfaces, mountains and clouds, but the irradiation variations are also moving winds and waves and evaporating water for useful precipitations for the growth of biomass and the river motions by gravity.

A logic solar harvesting concept offers all the roof surfaces on Earth, where energy is needed for heat and electricity, since buildings and their inhabitants consume about 1/3 of all energy. Even if we assume only one m2 useable roof space per inhabitant and only 10 % average PV and thermal efficiency, there are now over 6 Billion m2 or 6 TW (Terawatt, i.e. 6'000 GW) peak power at disposal at noon, or annually around 6 PWh solar energy in the form of heat and/or electricity available. This roof program alone would provide 5 % of the world energy needs - clean, sustainable and eternally available without energy cost, and providing many more jobs than with the resource intensive conventional systems.

Solar thermal energy can be directly used for hot water production from solar collectors of different types for different heat levels or be converted into electricity by different types of concentrator systems. Hybrid solar roof systems or cogeneration with solar power systems allow the simultaneous production of electricity and heat. See more details on all direct or indirect solar systems in the "Blueprint for the Clean, Sustainable Energy Age" -see order instructions below. Consult also the ISO and IEC standards for solar energy systems.

Once solar systems are mass produced like conventional, fossil energy systems, and integrated into buildings, thus replacing conventional roofs and facades they will become competitive and even more so if the external cost of polluting systems are fully taken into account. The solar electricity production can be enhanced by solar electricity exchange pools with the utilities, which already operate successfully in several countries.

There are also systems available for the daily and seasonal storage of solar heat and cold, combined with heat pumps, which can make buildings practically independent and pollution-free from conventional energy supplies. The ISEO solar energy committee is working on some case studies to be presented later on this website.

Solar air conditioning will be another important subject treated by ISEO, to be presented as soon as possible on this website.

An excellent example of successfully establishing and enforcing a law for the implementation of solar thermal roof systems is the Barcelona case - see web pages about the Barcelona solar law with a power point presentation on its positive results. This avenue shall be pursued in all nations and include also the PV integration in new buildings and building renovations.
