Solar power doesn’t have to be just for the wealthy anymore. With the right kind of financial incentives, households at all income levels can benefit from affordable clean energy.
Buyers and renters are very rarely told the energy rating of housing, but don’t blame the agents. As it’s voluntary for existing homes, very few are rated, so it’s not a big factor in the market.
Those endless cups of tea while working from home are unlikely to add much to your electricity bill. But coronavirus poses other problems for the electricity sector.
Australia requires a minimum six-star energy rating for new housing. New homes average just 6.2 stars, so builders are doing the bare minimum to comply, even as the costs of this approach are rising.
Air conditioning changed both building design and people’s active management of home temperatures. A return to houses designed for our climate can keep us comfortable and cut energy use and emissions.
Scott Morrison’s budget speech held no surprises on energy, after months of debate over the National Energy Guarantee. The real news comes in July with the release of a crucial ACCC report on power prices.
Our study found that office workers performed just the same, whether the air conditioning was set at 22°C or 25°C. But making that tweak can cut energy use by 18%.
