Below is an overview of some of the typical areas where renewable energy technology solutions can be applied. This is an indication of the type of opportunities available to you.
Wind energy
Small hydropower plants
Solar Energy
Biomass
Biogas production and utilisation
Geothermal energy and heat pumps
Renewable energy investments to switch from centralised to private supply:
In cases like this the investment to produce either biogas, electricity or heat (or all three) simply substitutes for some or all of the energy previously purchased from the centralised supply, or which is produced in-house. The cost of the investment is recovered from the savings from the energy not purchased from the centralised supply, a cheaper fuel, or a more efficient energy producing process. Decisions about fuel inputs, choice of technology, operation, reliability standards, and purchase of the energy are all made by the same organization, reducing the need for coordination among decision-makers, which significantly reduces the risk.
Some examples of renewable energy projects for own energy supply are:
Animal waste bio-digesters producing gas for CHP generation
Solar water heating for process hot water supply
Waste wood boilers for heat or CHP
On-site hydro or wind generation
Geothermal resources for heating or (if hot enough for steam) for electricity generation, and even for cooling (with absorption refrigeration).
