The only realistic alternative energy source is solar energy. The main obstacle to such a change is political. More than 70,000 copies of this book have been sold in several languages. Scheer received the World Solar Prize at the 1998 World Conference on Photovoltaics in Vienna. He insists this is not a distant dream but a realistic and urgently needed possibility today, which will overcome global economic disparities and the ongoing ecological crisis.
Renewable energies are inexhaustible.
They do not destroy the environment. They are available everywhere. Their use facilitates solidarity with future generations. They secure the future of humankind.
