A mandatory renewable energy target is a government legislated requirement on electricity retailers to source specific proportions of total electricity sales from renewable sources according to a fixed timeframe. The additional cost is distributed across most customers by increases in other tariffs. The cost of this measure is therefore not funded by government budgets (other than for the establishment and monitoring of the scheme and any audit and enforcement action. |

Overview
Renewable energy technologies are essential contributors to the energy supply portfolio, as they contribute to world energy security, reduce dependency on fossil fuels, and provide opportunities for mitigating greenhouse gases.[2] The International Energy Agency has defined three generations of renewable energy technologies, reaching back over 100 years:
- First-generation technologies emerged from the industrial revolution at the end of the 19th century and include hydropower, biomass combustion, geothermal power and heat. These technologies are quite widely used.[2]
- Second-generation technologies include solar heating and cooling, wind power, modern forms of bioenergy, and solar photovoltaics. These are now entering markets as a result of research, development and demonstration (RD&D) investments since the 1980s. Initial investment was prompted by energy security concerns linked to the oil crises of the 1970s but the enduring appeal of these technologies is due, at least in part, to environmental benefits.[2]
- Third-generation technologies are still under development and include advanced biomass gasification, biorefinery technologies, concentrating solar thermal power, hot-dry-rock geothermal power, and ocean energy.[2]
First-generation technologies are well established. However, second-generation technologies and third-generation technologies depend on further promotion by the public sector.[2] The introduction of mandatory renewable energy targets is one important way in which governments can encourage the wider use of renewables.
By Country
Australia
Commonwealth Government
The Australian Government has announced a Mandatory Renewable Energy Target to ensure that renewable energy obtains a 20% share of electricity supply in Australia by 2020. To ensure this the government has committed that the MRET will increase from 9,500 gigawatt-hours to 45,000 gigawatt-hours by 2020. After 2020 the proposed Emissions Trading Scheme and improved efficiencies form innovation and in manufacture are expected to allow the MRET to be phased out by 2030.
In May 2008 the Governments leading think tank, the Productivity Commission, claimed the MRET would drive up energy prices and would do nothing to cut greenhouse gas emissions. [3] The Productivity Commission submission to the climate change review, stated that energy generators have warned that big coal fired power stations are at of risk "crashing out of the system", and leaving huge supply gaps and price spikes if the transition is not carefully managed.
Computer modelling by the National Generators Forum has signalled the price on greenhouse emissions will need to rise from $20 a tonne in 2010 to $150 a tonne by 2050 if the Rudd Government is to deliver its promised cuts. Generators of Australia's electricity warned of blackouts and power price spikes if the Rudd Government moved too aggressively to put a price on greenhouse emissions. [4]
Climate Change Minister Penny Wong has reaffirmed that the Government will proceed with its mandatory renewable energy target of 20 per cent of supply by 2020. The renewable energy industry has backed the commitment, claiming a 20 per cent target was the global standard for climate change policy.[4]
States
The Commonwealth and the states agreed in December 2007 at a Council of Australian Governments (COAG) meeting to work together from 2008 to combine the disparate state schemes with the Commonwealth scheme into a single national scheme. The initial report on progress and an implementation plan are expected to be considered at a March 2008 COAG meeting with a final design to be presented for consideration at the September 2008 COAG meeting.
