Powering a country on renewable sources is possible. The Costa Rican Electricity Institute (ICE) announced that the country achieved “99 percent renewable electricity generation” this past year. For 285 days of the year, the country’s grids were powered completely by renewable resources. A majority of renewable electricity generation comes from hydroelectric plants, which takes advantage of […]

There are millions of people in the world who have little to no access to energy of any kind, much less clean energy. Here in South America, the highlands of Perú specifically, I find it interesting that there are more people with mobile phones than with televisions. Communication is very important to these people, in […]

Solar power drives everything on this planet, from ocean currents to the trade winds, all of which could be used to generate electricity for the increasing power demands of human civilization. Ocean currents can be harvested for their energy, but the equipment to do so has often been expensive and limited in scope. Previous generations […]

Ten years ago, a report based on measurements taken at a hydroelectric plant in Brasil said that the gas (CO2 and methane) emissions of hydroelectric power (HEP) reservoirs account for 1 to 28% of the total greenhouse gas emissions caused by man. The report said that the CO2 and the methane came from the rotting organisms contained in the HEP reservoirs.
