Technical information can be vital to bringing resources to needy communities, and all those involved in development need access to it. Green Empowerment's partner in Peru, Practical Action, meets this need through the Practical Answers service. Learn more or submit an inquiry here.

 Micro Hydro Systems (en espanol)
All energy produced by using falling water to turn a turbine is considered hydro-power and is often grouped with renewable energies, but not all hydro-power is benign. Small-scale hydro projects have very minimal environmental impacts and avoid the displacement of local populations. Solar Power The sun is the earth’s most powerful energy source and slowly people are finding new ways, and recovering old ways, of using that solar energy. Solar Pumping Systems As more and more groundwater sources become unsafe for drinking purposes, potable water often needs to be drawn from depths that require some form of pumping. Additionally, if the potable water source is far from the community, solar pump systems may be a viable solution to distribute the water.
Ram Pumps
Ram pumps are simple mechanical devices used to pump water uphill for irrigation or potable water distribution. They don't use any electricity and with only two moving parts, are easy to build and maintain.
Biomass
Biomass includes everything from firewood, to vegetable oil, to rice hulls, to cow dung. Biomass is burned by much of the world’s population for cooking and heating. There are also techniques to refine biomass into more efficient fuels such as alcohol, methane or charcoal. Wind Wind power is the world’s fastest-growing energy source and “wind farms” are sprouting up from India to the American Midwest. The amount of energy generated by wind has nearly tripled between 1995 and 1999. Geothermal The heat energy from below the earth’s crust can be converted into electrical energy. The most common type of geothermal energy is hydrothermal which uses the hot water and steam formed where molten magma heats ocean or groundwaters 100m to 5km deep. |
