Mojave Desert uses light reflected by mirrors to heat molten salt to 565☌ (1050☏). This experimental solar power station in Californias Too far north or south (if you want electricity in the winter, at least). Location where the technology is to be used.Īrid areas with few cloudy days are ideal locations for solar power, as long as they arent Harnessing a natural renewable energy resource must be adapted for the Need accurate data collected over a long period of time. Specifically, for any given locale, engineers They need to know how much of a given type of energy is available, and Before engineers can develop such technology, Who need it mostfor people to tap into these and other sources of What is lacking is the technologyat an affordable price for those Turbines can easily capture enough of this wind energy to, say, power In certain areas, there is often an abundance of wind energy. There is ample sunlight to power many of the peoples basic needs. Most of these are tropical countries where, ironically, Many people who live in underdeveloped countries spend more of theirĭisposable income on fuel for cooking food than they have to spend onįood itself. AlternativeĮnergy sources such as solar power and wind energy can provide necessary energy, but they need to be placed in appropriateĪreas with enough sun and wind. Such fuels are dirty and inefficient, and often in short supply. These regions are dependent on fuels such as wood and animal dung for In much of the world there is no elecricity, no deliveries of home heating oil,Īnd no natural gas piped into the home. YouĬould even power most of your home, except for heating and air This energy could be used to, say, bake a chicken or boil a stew. Receive at least 4 kilowatt hours of sunlight per square meter per day. Hour is greater than the amount of energy used by the EarthsĮntire population in a year. The sunlight that reaches the Earth every Take advantage of those sources of energy that nature gives us freely,Īnd replenishes constantly. But we must also aggressively explore how to better Plants so we can burn more coal and fossil fuels to feed our insatiableĭemand for power. Western world are accustomed to thinking in terms of building more power Of the power resourcesall of the resourcesavailable to us. The issue is we humans dont effectively and efficiently make use The issue in most of these cases is not too little power. Portions of the state of power, seemingly at random.įor more information about NASA’s Surface Meteorology and Solar Energy Project, visit the home page (a new browser window will open).
