Perspective

"The transition from fossil fuels to renewable resources is a long and expensive but an absolutely vital process. We need a long term (30 to 50 years), high-priority program using a substantial part of the GNP and covering the entire scope – from fundamental research to commercial installation strategy – to gradually replace the fossil fuels we use for power generation, transportation and industrial thermal energy."
