The greenhouse effect is the process whereby greenhouse gases (GHGs) in the atmosphere absorb the radiation released by the Earth’s surface and then radiate heat in all directions, including back towards the ground and water. Altogether this adds to the heat the Earth receives from the Sun.
The release of GHGs stored in fossil fuels to produce electricity adds to the greenhouse gas effect and is a cause of rising temperatures within the Earth’s atmosphere. The Department of Environment and Energy in 2018 reported an emissions factor of 0.82 kg CO²-e/kWh for electricity consumed through the National Energy Market (NEM) with the electricity sector accounting for approximately one third of Australia’s national GHG emissions.
Implementing renewable energy projects avoids emitting CO2-e that would otherwise be produced from burning fossil fuels. These emissions reductions contribute to Australia’s national emissions reduction targets and can also contribute to the sustainability goals of your own organisation. They will ensure a high standard of living for both current and future generations.
Air and water pollution emitted by fossil fuel mining and combustion contributes to a range of health conditions affecting the cardiovascular, respiratory and nervous systems.
Exposure to pollutants may cause or exacerbate asthma, chronic obstructive pulmonary disease and lung cancer.
Toxic particles in pollution can also cause inflammation in distant parts of the body, leading to heart attacks and strokes.
Chronic exposure to pollution can result in mercury poisoning and impaired brain development, particularly in children.
The healthcare sector is a major contributor to Australia’s carbon footprint, estimated to be more than 7% of Australia’s national emissions.1 Hospitals are the largest emitters within the sector followed by pharmaceuticals with emissions predominantly coming from energy use, transport, and products manufactured, used and disposed of.
Renewable energy that displaces energy generation from fossil fuel will reduce pollution and emissions thus having a positive impact on heath
Affordability & Reliability
Electricity prices have been on the rise recently due to several factors including increases in network costs due to the roll out of smart meters as well as upgrading network infrastructure such as poles and wires to account for high peak load, rises in wholesale electricity prices, environmental costs and increases to retail margins and costs.
Compared with traditional forms of generating electricity from the combustion of fossil fuels, the generation of electricity from renewable sources offers stable energy prices which are not exposed to fluctuations in fuel prices, supply issues, or transport costs. Renewable energy is a reliable source of energy with low operating costs and zero greenhouse gas emissions once the embodied emissions have been accounted for.
Currently, it is cheaper to generate electricity from a solar PV system on your roof than it is to purchase electricity from the grid through a retailer. Rooftop solar PV avoids the transmission, distribution, retail, wholesale and environmental charges found out your bill. Furthermore, if you generate more electricity than you need, you can earn an income from the excess power sold to the grid.
