What is RENEWABLE ENERGY? |
Renewable energy sources contribute approximately 29.3% of the human energy use worldwide. The prime source of renewable energy is sola radiation, i.e. sunlight.
Fossil fuels like coal, oil and natural gas have provided us with economical and convenient energy sources for years, but they are finite resources, and their use has come at an environmental cost.
Renewable energy sources present the prospect of energy utilization with minimum impact on the environment, particularly in relation to greenhouse gas emission.
Commonly known renewable technologies include:
Electricity produced by hydropower. Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator, although less common variations use water’s kinetic energy or dammed sources, such as Tidal Power where the energy contained in moving water in tides and ocean currents is used.
Electricity produced by the use of geothermal heat. Geothermal comes from the Greek words geo, meaning earth, and therme, meaning heat. Geothermal literally means “earth heat”.
This is the conversion of wind energy into more useful forms, usually electricity using wind turbines. Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator.
This is the technology of obtaining usable energy from the light of the sun. Solar energy has been used in many traditional technologies for centuries and has come into widespread use where other supplies are absent, such as in remote locations, and in space.
Biomass refers to living and recently living biological material, which can be used as fuel. Most commonly, biomass refers to plant matter grown for use as biofuel, but also includes plant or animal matter used for production of fibres, chemicals or heat. Biomass may also include biodegradable wastes that can be burnt as fuel. It excludes organic material which has been transformed by geological processes into substances such as coal or petroleum.
-------------------------------
Renewable electrical power is becoming cheaper and convenient enough to place it, in many cases, within the reach of the average consumer, the possibility to value add your waste.
Renewable heat is an application of renewable energy, i.e. the generation of heat from renewable sources. In most cases, contemporary discussion on renewable energy focuses on the generation of electrical, rather than heat energy.
On an annual basis the United Kingdom consumes 350TWh (12) of electric power, and 840 TWh of gas and other fuel for heating.

Renewable Energy Power Generation |
A factory in Gladstone, QLD, produces 11 million ice-cream sticks a day.
The waste created from the production of the ice-cream sticks is then burned to produce the energy to dry the sticks.
The waste is used as part of the process.
A meatworks, operating 8,000 hours per year, was spending around $1,000,000 a year on power, as well as having to dispose of waste produced.
The meatworks now spends around $500,000 per year on power, that’s a around a 50% decrease in the cost of powering their business!! And they no longer need to dispose of their waste externally – it has been incorporated into the process of producing the energy to run the meatworks.
Australia’s saw milling industry:
A medium sized mill generates 50,000-100,000 tonnes per year of wood waste.
The latest development in Biomass combustion systems allows the combustion of wood waste from the mill that normally went to land fill to be combusted to meet the EPA requirements of 100mg/m3 and generate power.
