Low Carbon West

Councils are taking responsibility to reduce carbon emissions – leading the way by reducing their own emissions and assisting community action. But to transform a whole region to a low carbon economy, councils need to do more. They can collaborate on large-scale projects across municipalities, create opportunities for businesses from sustainable, low-carbon growth, and coordinate programs to increase their reach to communities, strengthen their messages and improve liveability. The Western Alliance for Greenhouse Action (WAGA) is a partnership of eight councils in the west of Melbourne, representing a cross-section from urban (Brimbank, Hobsons Bay, Maribyrnong and Moonee Valley), to growth …

Compost could be harnessed for clean energy production

A 2015 Churchill Fellowship recipient says his research has shown there is huge potential to generate clean energy from compost. Gippsland Water agribusiness manager Jono Craven has just completed his fellowship report, titled ‘The Investigation of Effective Recycling of Urban and Agricultural Waste to Provide Positive Outcomes for Agriculture’. Mr Craven said he adopted the topic to try and work out how to get better agricultural results out of compost. He travelled to Israel, the UK, Germany, Austria, the Netherlands, the US and Canada to research best practice compost production. “Before I left I saw varying results through the use …

Investors keen to back Western Australia’s largest solar farm

The company behind a proposed $160 million solar farm in Western Australia’s Wheatbelt says it has been spoilt for choice when it comes to investors. Sun Brilliance Power plans to start building a 100 megawatt solar farm, the largest in Western Australia, early next year and will be finalising financial agreements at the end of October. What was originally designed as a 25 megawatt facility has been expanded four-fold after the company purchased what it described as an ideal location two kilometres east of Cunderdin in May this year. Spokesman for the company, Ray Wills said it would be the …

Renewable Energy In Cities – IRENA Report

Making up 65 per cent of global energy use and 70 per cent of anthropogenic carbon emissions, cities must play a crucial role in the shift to a low-carbon economy says IRENA. A new report from IRENA focuses on best practice gleaned from thousands of cities around the world making up 60% of global energy demand, demonstrates what is possible and details the sorts of policies required to enable the change. “We have to rethink the entire urban energy landscape, which requires rigorous planning and holistic decision-making,” said Adnan Z. Amin, IRENA Director-General “Renewable energy, combined with energy efficiency, will …

The gas industry needs a carbon price to compete with coal

Putting a price on carbon would benefit the Australian gas industry, at least in the short term. It is therefore in the interests of gas producers to lobby for the emissions trading scheme proposed for the electricity industry by the Climate Change Authority. At first a sight this might seem a paradoxical suggestion. Isn’t carbon pricing meant to reduce our reliance on fossil fuels after all? But with gas prices high, coal-fired generation has been increasing. Coal produces about twice as much carbon dioxide as gas when it is used to generate electricity. This is bad news for our emissions, …

Wood pellets proposed to replace coal used by thermal power stations

A renewable replacement for black coal burned in thermal power stations could be made by converting Tasmanian plantation wood into a pelletised biomass fuel. Private equity firm New Forests has started a $5 million feasibility study into a $130 million wood pellet plant for Tasmania’s Tamar Valley. If approved, New Forests’ hardwood plantation subsidiary, Forico, would supply 100 per cent FSC-certified plantation hardwood and softwood to the bioenergy pellet plant, according to Forico chief executive Bryan Hayes. “These pellets are able to go into an existing power plant without any modifications whatsoever,” Mr Hayes said. “These black pellets will directly …

How New Systems Can Make The World A Greener Place

Global energy consumption has grown steadily over the past century. This trend, driven by population and economic growth, is set to continue in spite of rising efficiency of both production and consumption. The IEA estimates that over the period to 2035 the investment required each year to supply the world’s energy needs will rise steadily to $2,000 billion. In response to new opportunities such as renewable energy and smart technologies – and new policy goals – to reduce emissions and extend energy access, Distributed Energy Systems (DES) encompasses a diverse array of generation, storage, energy monitoring and control solutions. DES …

Rushing to renewable energy targets puts sector’s reputation at risk

The last time an entire state blacked out was on the night the Beatles arrived in Sydney in 1964. So what happened in South Australia last week was rare and the repercussions could be vast. The key question is whether that state’s heavy reliance on wind turbines might have increased the risk of a state-wide blackout. More broadly, the event will supercharge concerns over how renewable energy is being integrated into a national grid that was not designed to cope with it. Wind presents two problems. First, it is intermittent, so all of it has to be backed up by …

Does rapid renewables expansion mean higher electricity prices?

Perhaps one of the many points coming out of the Grattan Institute’s latest report is the idea that rapid expansion of renewable capacity must necessarily mean higher electricity prices. But what has been the experience in Europe over the last five years during which there has been a rapid expansion of renewable capacity in most European countries? The Council of European Regulators compiles useful information on retail and wholesale electricity prices. Here is a table compiled from their data, which shows their estimate of average wholesale electricity prices (in Euros per MWh) in 2008/9 and 2014 in various European countries. …

Move to clean energy requires smart policy

The phrase “sovereign risk” is used liberally in Australian public debate, most often in relation to established industries that may be affected by change in federal and state policy. But few have suffered as much as the still-establishing renewable energy sector, which has had to deal with constant chopping and changing in government thinking since the turn of the century. This has particularly been the case since the election of the Abbott Coalition government in 2013. With an axe hanging over the renewable energy target and the abolition of the Labor-Greens carbon pricing scheme, there was a 70 per cent …
