Renewable Energy and Energy Efficiency

When you want substitute fossil fuel, you can either use technology or develop a bio fuel.

Any technology shift is a chance for copper.

Copper can be found in Solar PV, Solar Thermal, Bio mass heat exchangers, Ocean technology, Wind Mills and others.

ICA plays a leading role in Slum electrification projects, Grid integration, Street Lighting projects, Renewable Energy technology transfer

ICA is sponsor of Policy work for Renewable energy and Energy Efficiency and out reach programs.
