This chapter has indicated that there are innovations, business potential, and new jobs to be had in the following areas:
*   wind turbines;
*   photovoltaics (PV) (i.e 'solar panels') - producing electricity directly from the    sun's energy;
*   solar thermal  (e.g. solar hot water systems, solar pool heating, producing steam to    generate electricity);
*   biomass - land fill gas (LFG), bagasse (sugar cane waste which is burned to    produce electricity), biogas (i.e. methane from sewage or piggery waste), ethanol    (liquid fuel derived from plant matter), and, traditional wood burning;
*   hydropower;
*   tidal and wave energy;
*   energy from waste; and,
*   geothermal.

Energy efficiency opportunities are even more varied as they can include practices and simple behavioural changes which save energy. Some general energy efficiency business opportunity categories include:
*   energy efficient lighting, eg. compact fluorescent lamps, lighting control systems    for large buildings; energy efficient appliances, eg. fridges, space heating, hot    water heaters, low-flow shower heads;
*   energy efficient vehicles;
*   energy efficient building design, eg. passive solar architecture; and, energy    efficient building materials, eg. 'smart windows', insulating bricks, wall & roof    cavity insulation, awnings and pergolas
