To Our World Environment: Water, Energy, Waste Management

Three key objectives of India’s energy policy: [1]

Energy Access Energy Security Climate Change

In principle, these objectives are contraditory

How can technology help to achieve these objectives?

Technology can help developing more efficient and low cost equipments, but some priority choices must be made and followed

To strength the contradiction of energy policy, the use of renewable energies is important for many reasons, but the amount of usable energy is not enough to guarantee energy security.

To use solar photovolaics for energy access, stand-alone systems must be used to provide energy for rural areas

To Our World Environment: Water, Energy, Waste Management

Low cost, robust and more efficient equipments must be designed. Photovoltaic panels are still too expensive and their efficiency is low

Electronic converters are expensive, not robust enough for rural applications and yet of difficult maintenance

The installation of the system is not enough, its maintenance is very important

People must me educated and trained to help in the maintenance effort

Popularization of science and technology is an important task, and Universities play an important role for this

To Our World Environment: Water, Energy, Waste Management

Solar thermal has an important role also, not only for energy generation, but also for home applications like cooking and food refrigeration

And independently of political choices, to provide better conditions for poor people it is necessary the solidarity of everyone

To help poor people, my equation is:

less poverty = education + technology + solidarity
