25 October 2017, ENOVA One Step Off the Grid: Enova launches community “Solar Garden” for those who can’t install. NSW community energy retailer Enova has launched a first-of-its kind project that will enable renters and others who can’t intall rooftop solar to invest in a “solar garden” and benefit from reduced bills. The idea is to build a 99kW rooftop solar system – most likely on a business – and “sell” the panels in 1kW chucks to consumers that can’t put solar on their own roofs, either because they are renting, they live in apartments, in houses that are shaded, or can’t afford to invest in a whole system. Enova held a public meeting in the northern Rivers town of Brunswick Heads on Tuesday to sell the idea, which it says could be the first of many such “solar gardens”, particularly as it moves into the major metropolitan markets of Newcastle and Sydney early next year. “We’ve been thinking about this for a while,” Enova chair Alison Crook said. “People have been saying they want to install solar but they can’t do it …. this makes rooftop solar more affordable and accessible for everyone. We didn’t think that we’d be able to offer this so quickly – but it is here.” The savings from a solar garden are not as great as having your own rooftop solar, but according to Enova’s numbers they are substantial, and can offer a rapid payback time. Customers will be able to buy capacity in increments of 1kW. The upfront price is expected to be $1,000 for each 1kW, and the returns could up to to 23 per cent a year (in the form of a $230 reduction in annual energy bills for each kW). That represents a payback of less than 5 years. The deal lasts for 20 years. Read More here

28 September 2017, Australian Institute, Climate outliers: Australia and Turkey the only developed nations breaking emissions records. The Australia Institute’s new Climate & Energy Program has released the National Energy Emissions Audit. The Audit, compiled by renowned energy specialist Dr Hugh Saddler, provides a comprehensive, up-to-date indication of key greenhouse gas and energy trends in Australia. “The report finds, disturbingly, that Australia’s annual emissions from energy use have increased to their highest ever level, higher than the previous peak seen eight years ago, in 2009,” Dr Saddler said. “Australia’s failure to invest in efficient transport infrastructure, such as rail, has led to emissions from transport fuels continuing to grow, again, unlike the rest of the developed world. “The continued rise in fuel emissions demonstrates why requiring a reduction for the electricity sector that is only equal to the Paris target would likely see Australia fail to meet its international commitment,” Dr Saddler said. Key findings:
- Australia’s energy emissions continue to increase, breaking all-time record
- Among developed nations, only Australia and Turkey are breaking emissions records
- Petroleum, in particular diesel consumption is the main driver of emission increases
- There is no indication of when or if growth in petroleum emissions will stop Read More here
6 September 2017, IOL Motoring The hydrogen vs battery car debate is far from over. London – With hybrid and full electric cars now becoming mainstream, it may seem as though the early debate between hydrogen and battery power is over. But batteries have considerable drawbacks. They’re heavy, they’re expensive, they require the extensive use of rare earth metals, and the production of lithium-ion batteries is itself an energy-intensive process that creates considerable emissions. Despite the progress made in EV technology, most car companies are predicting it will be a long time before batteries become dramatically cheaper or lighter than they are today. Speaking to investors last year, Stefan Juraschek, vice president of electric-powertrain development at BMW, said the car maker needed to “walk through the valley of tears” of funding highly costly research and development in order to make significant progress on battery power. Electric cars require energy straight out of the mains, which could come from power plants that are not using renewable technology. In Tesla’s home state of California, 60% of electricity was provided by coal and gas power stations in 2015, while only 14% came from wind and solar. China is investing more in renewables than any other nation yet derived roughly 72% of its electricity from coal power in 2014. In a hydrogen fuel cell car (FCEV), electric motors power the wheels but the energy is supplied through a chemical reaction between hydrogen and oxygen in the fuel cell. Unlike the rare and heavy components needed to build a battery, hydrogen is the most abundant and lightest element in the known universe although it is worth noting that hydrogen drivetrains also require rare materials.

4 September 2017, One Step Off the Grid, Community retailer Enova to buy and sell rooftop solar power, Australia’s first community-owned energy retailer, the Northern Rivers NSW-based Enova Energy, will soon offer customers locally generated rooftop solar power, as part of its goal of producing enough renewable electricity to meet all of its customers’ needs. In a statement released late last week, the company said it would now purchase excess rooftop solar generation from its customers, as well as from local community solar farms and gardens, to sell on to other customers who wanted access to solar power, but could not generate it themselves. The new scheme, which Enova says could meet just under half of existing customer requirements, comes less than two months after the retailer boosted its solar feed-in tariff by 33 per cent, to 16c/kWh. “Using solar supplies such as (the new 18kW system on our own office rooftop in Byron Bay) ….we can now supply locally generated renewable energy to people who don’t own their own solar panels,“ Enova said in a statement late last week. “Enova can meet approximately 40% of existing user requirements with this locally generated renewable energy.” The retailer said that it was also introducing new energy plans to allow customers to access the community generated solar.
