READ MOREHydro energy. As a renewable energy resource, hydro power is one of the most commercially developed. By building a dam or barrier, a large reservoir can be used to create a controlled flow of water that will drive a turbine, generating electricity. This energy is: Reliable. Easy to store. Cheaper to setup than other renewable sources.
READ MORERenewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in
READ MORERenewable energy sources are those that are naturally replenished on a relatively short timescale. Renewable energy sources include solar, wind, hydroelectric, and geothermal
READ MOREThe most obvious and widely publicized barrier to renewable energy is cost—specifically, capital costs, or the upfront expense of building and installing solar and wind farms. Like most renewables, solar and wind are exceedingly cheap to operate—their "fuel" is free, and maintenance is minimal—so the bulk of the expense comes from

READ MOREAt least 29 U.S. states have set renewable portfolio standards—policies that mandate a certain percentage of energy from renewable sources, More than 100 cities worldwide now boast at least 70
READ MORESources of energy can be classified into: Renewable sources of energy are available plentiful in nature and are sustainable. These resources of energy can be naturally replenished and are safe for the environment. Examples of renewable sources of energy are: Solar energy, geothermal energy, wind energy, biomass, hydropower and tidal
READ MOREThe term "renewable" encompasses a wide diversity of energy resources with varying economics, technologies, end uses, scales, environmental impacts, availability, and depletability. For example, fully "renewable" resources are not depleted by human use, whereas "semi-renewable" resources must be properly managed to ensure long-term
