Forms of Renewable Energy 

Biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter.

Concentrated solar power (also called concentrating solar power, concentrated solar thermal, and CSP) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator

Hydropower or water power is power derived from the energy of falling water or fast running water, which may be harnessed for useful purposes. Many any kinds of watermills have been used as a renewable energy source for irrigation and the operation of various mechanical devices, such as gristmills, sawmills, textile mills, trip hammers, dock cranes, domestic lifts, and ore mills. Hydroelectricity is produced using Hydropower.  There are resources relating to possible hydropower projects in regional communities on the Pumped Hydro (Community Energy)  Storayge Seymour and Strathbogie  web page.

Pumped hydropower which generates clean energy  using the excess pressure that builds up in gravity-fed water pipes between elevated reservoir sources and customers to drive a hydro turbine and generate electricity is discussed  in  "Victoria University engineers tap into  a clean source of energy" A publication by the US Department of Energy also considers such options - 'Pumped Storage and Potential Hydropower from Conduits' Report to Congress 2015 .

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect.

Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter 

Wind power is the use of air flow through wind turbines to mechanically power generators for electricity. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land.
