Diesel generators are expensive consid- design for improved efficiency, modular ering rising fuel prices and risk fuel-spill design for customized installations, pollution. Alternatives such as windmill easy set-up, and a reputation for pumps impose other challenges. longevity. In many cases this solution offers a comparable or lower cost com- pared to a grid-power installation, as well as offering energy independence with a low environmental impact.
