Solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors and a fluid system to move the heat from the collector to its point of usage. Systems may use electricity for pumping the fluid, and have a reservoir or tank for heat storage and… Continue reading Solar hot water
Geothermal energy is energy derived from “warm areas” below the earth’s surface. This can provide a carbon emissions-free energy source.
“Clean coal” is a term coined by industry and government to describe as yet unproven methods of burning coal for producing energy with reduced carbon emissions. The term is actually misleading as burning coal for energy will never result in zero emissions. The term “clean coal”, which has been described by some as an oxymoron[1], is… Continue reading Clean coal
The Carbon Pollution Reduction Scheme (CPRS) is an emissions trading scheme proposed for introduction in Australia in late 2010. Summary of criticisms The structure of the scheme has been widely criticised, including by the Government’s previously appointed climate change policy adviser [Professor Ross Garnaut] [1], for the following reasons: Structure The structure of the CPRS is not yet finalised.… Continue reading Carbon Pollution Reduction Scheme
A feed in tariff provides a fair price for solar electricity generated on rooftops and fed into the electricity grid. Moving towards renewable energy is an essential means of addressing climate change, and solar photovoltaic (PV) micro-generation has an important role to play in boosting renewable energy. By offering a premium price for electricity generated on rooftops… Continue reading Feed in tariff
The Garnaut draft report on economic measures and actions to address climate changes was released on July 4, 2008. The main points included in the Garnaut draft report are: Praise Criticisms Professor Garnaut’s much-awaited Draft Report has been criticised for being strong on the architecture but terribly weak on the big, over-riding issue of preventing runaway climate change.… Continue reading Garnaut draft report
Geothermal energy is energy derived from “warm areas” below the earth’s surface. This energy can be obtained by circulating a fluid through pipes between the surface and the warm area below, which can then be extracting using a heat pump. This article describes geothermal “warm areas” in Australia. Geothermal energy in Victoria In Victoria if the geothermal… Continue reading Geothermal in Australia

The Drake Landing Solar Community is the first community to be completely solar powered for heating in North America. It is located within the town limits of Okotoks, Alberta, Canada. This development provides a working example of how simple living a green lifestyle truly is. There are over 800 solar panels on garage roofs, responsible for the… Continue reading Drake Landing solar community
Distributed energy storage offers potential to make renewable energy such as wind and solar power more effective and more economic. The concept is to store energy from renewable sources during peak energy production close to where it is produced, so that it can be used during lower energy production periods. For example, solar panels can generate… Continue reading Distributed energy storage
