Last week the world's atmosphere took a giant leap backward. For the first time in more than 3 million years, the atmospheric concentration of carbon dioxide (CO2) reached 400 parts per million. This was recorded at the National Oceanic & Atmospheric Administration's Earth System Research Laboratory located on Mauna Loa in Hawaii right out in the middle of the Pacific Ocean, a long way from major sources of CO2 in Asia and North America. What this means for the environment is uncertain but it's likely that, if no measures are taken to reduce this level of greenhouse gas, we could be headed for 3-4 degrees C warming globally by the end of this century
Today, we produce about four billion metric tonnes of food per annum. Yet due to poor practices in harvesting, storage and transportation, as well as market and consumer wastage, it is estimated that 30-50% (or 1.2-2 billion tonnes) of all food produced never reaches a human stomach. Furthermore, this figure does not reflect the fact that large amounts of land, energy, fertilisers and water have also been lost in the production of foodstuffs which simply end up as waste. This level of wastage is a tragedy that cannot continue if we are to succeed in the challenge of sustainably meeting our future food demands.
But how much can wind farms and solar panels contribute to a solution? Are they really the best option for Australia's energy future? And what part does the media play in the communication of all of this?
The Science behind the headlines event (22 May 2012) held by RiAus attempted to answer these questions by combining a panel of scientists with experienced journalists - led by RiAus Programs Co-ordinator James Byrne. Each of the participants' knowledge of their specific field made for a varied and vibrant discussion that covered a wide range of topics. Is the public really aware of alternative energy options?
ARENA is pleased today to highlight a new solar map website, which tracks the contribution of solar photovoltaic (PV) systems in Australia's energy mix and provides a guide to the location and capacity of PV installations across the country.
"Contrary to many claims, the costs of renewable energy are minor. In 2015, probably the earliest any major changes to the policy could be made, the RET would cost the average household around $1 a week."
"These maps are based on data from the Clean Energy Regulator, the Australian Government agency tasked with the administration of the Renewable Energy Target. For each postcode and local government area, the map shows the estimated percentage of dwellings that have a PV system and the total photovoltaic capacity installed. Most of the PV systems in Australia are small-scale rooftop installations; however there are a number of larger-scale PV power stations with a capacity of more than 100 kW. These power stations are indicated by individual markers. Live performance data is available for systems in the Desert Knowledge Precinct in Alice Springs, and at the University of Queensland."
The Grattan Institute report looked at how viable a carbon price would be for Australia's largest industries. In this Slow TV video, report authors John Daley and Tristan Edis show how a carbon price won't bring about job losses, increase prices or send big business broke.
