Sustainable Development

Energy + Ecology + Economy

Energy & Environment Convergence

Economic progress requires convenient and affordable forms of energy Energy is cause of most damaging and intractable environmental problems Challenge is to meet energy/economy needs without disrupting environment Sustainable development = means and end are consistent.

Energy Environment and Economy

Average temperature of earth is rising Up 1.2 degree in last 100 years, 0.9 in last 30yrs 12 hottest years since 1860, all after 1980, 5 after 1990

Evidence is unrefutable: Evaporation & rainfall on the increase Glaciers are retreating Sea ice & snow cover are shrinking

Climate Change Evidence

Solar: Affordable Clean

Energy Solution

Sustainable ‘GREEN’ Technology

An investment in a solar energy system delivers the following benefits:

Solar is a fixed cost hedged against rising energy costs. Solar provides a compelling return on investment and payback as low as 3 years in some cases. Solar energy systems are highly reliable and have low maintenance costs. Solar is a clean, completely silent energy generation technology.
