Developing countries are witnessing rising demand for the use of clean energy services. USAID is engaged in such development programs as these and Tetra Tech is assisting it by designing clean energy strategies.

Further, Tetra Tech will assist USAID in the latter’s efforts to reduce global warming and design technologies which will help in achieving energy efficiency and carbon sequestration. The program also includes improvement of foreign and local government capacity in the energy sector to handle natural or man-made disasters.
