Problems with the present energy system
i. Exhaustion of fossil resources
ii. Security of supply
iii. Environmental impacts

Environmental ImpactsProblem Main cause
Local • Urban air pollution• Water availability• Soil degradation• Toxic and dangerous substances
• Fossil fuels for transportation• Solid fuels (biomass and coal) for heating and
cooking.
Regional • Acid rain • Emissions of sulphur and nitrogen oxides
particulate and ozone from fossil fuels
Global • Reduction of the ozone layer• Climate Change• Coastal and ocean degradation• Deforestation• Biodiversity loss
• Emissions of CO2 from the burning of fossil fuels
• Extraction of timber, charcoal production and
expansion of the agricultural frontier.• Transportation of fossil fuels
Modern renewables projections for 2010 and 2020

TECHNOLOGICAL LEAPFROGGING
Rather than mimicking the industrialized nations, going
through an economic development phase that is dirty and
wasteful creating a enormous legacy of environmental
pollution, developing countries can leapfrog over some of
the steps originally followed by industrialized countries and
incorporate currently available modern and efficient
technologies into their development process.
