Queensland develops a simple energy efficiency investment program for commercial buildings and their tenants

Brisbane city (TheFifthEstate)

An industry-led program called t3, has been developed by Incorp and Brisbane City Council’s sustainability agency CitySmart. It is a simplified Environmental Upgrade Agreement (EUA) process that gives building owners and tenants incentives to pursue energy efficiency upgrades, with both guaranteed a share in savings generated.

t3 operates on a cost recovery basis where building owners fully fund the upgrade but then receive 80 per cent of the operational savings over the term of a lease. Tenants have no capital outlay, but keep 20 percent of savings (though different splits can be negotiated). Carbon credits generated from projects are also donated to a chosen charity.

Initially, two institutions have signed up to t3: building owner Queensland Investment Corporation (QIC) and tenant Queensland Department of Housing and Public Works. The deal involves an upgrade of lighting from fluorescent to smart LED over two buildings at 111 George Street and neighbouring 33 Charlotte Street in Brisbane CBD. The plan is to add other energy efficiencies such as solar power and further improvements later.

If this t3 initiative is expanded it could deliver $100 million a year in savings to Australian businesses while cutting annual greenhouse gas emissions by 180,000 tonnes. Incorp works across many borders – Sydney, Melbourne, Brisbane, San Francisco, Seattle and Dubai. Maybe this is exactly the right company to help spread the idea.

A new solar reality for Australia and the Globe

Scientia Professor Martin Green of the University of New South Wales speaks for Ockham’s Razor about the falling costs of renewable energy, particularly solar power, and how this will affect our future.

It is now less expensive to install new renewable energy than it is to build new coal-fired power stations, so the installation of renewables will increase over time. On current projections, Australia could get most its electricity from renewables by 2050.

Globally, 40% of our CO2 emissions come from electricity generation but fortunately we can do something about this by adding renewable power. Other significant emitters are passenger cars (10%) and this too can be reduced if our electricity comes from renewable energy and we drive electric vehicles.

Cars have been developed with their own solar panels that can charge a car battery to do an average 25 km/day. That is close to the average distance a car travels daily. Toyota sees this development as a way to substantially reduce the CO2 emissions from hybrid cars.

Australia's first large-scale solar and battery plant is connected.

The first large-scale solar and big battery storage installation in Australia - the Lakeland project near Cooktown in far north Queensland - has been officially connected to the grid. It is at the edge of the very large electricity grid of eastern Australia where electricity supply is not always reliable.

With a smallish population to support, it is a relatively small system of 10.8KW of solar and 1.4MW/5.3MWh of battery storage. Importantly, the system will firm up supply of solar power to the grid and provide ‘islanding’ for the local community whereby homes and businesses can remain connected while there is a fault elsewhere.

This deliberate ‘islanding’ will be a test case where a section of the grid continues to provide power while disconnected from the main grid. A test case that could prove to be important for those areas that are at the extremes of grids or prone to natural disasters such as bushfires, cyclones or floods.

Tree planting is increasing around the world

We are learning that trees have far more value than providing timber: they keep soils moist, prevent floods and provide shelter, store carbon, beautify landscapes, protect water sources, increase biodiversity, improve conservation, have a cooling effect through transpiration and induce human wellbeing.

Many countries have ambitious projects to plant large areas of trees. Some include: China, India, Ireland, Norway, France, England, Costa Rica, Nepal, Peru and Mongolia. Latin American countries pledge to restore 20 million hectares of degraded forest and African countries more than 100 million hectares. Most of Europe is now physically greener than what it was a few years ago. More than 120 countries in 2015 pledged to plant and restore large areas of forest as a response to climate change. The UN has set a target to restore 350 million hectares by 2030.

However, deforestation and land degradation is still occuring around the world which weakens the land’s resilience. Forests are also under threat from climate change related threats such as droughts and bushfires. Mass, state-sponsored plantings are not always successful. The growth of agroforestry is providing a solution where trees and shrubs are grown among crops (and stock). In some countries, such as Niger, this approach has increased yields as compared to their broadacre cropping.

Are new home builds with solar and battery to become the norm?

Major Australian home builder Metricon, offers to build new homes with solar panels, battery storage and, if desired, an electric vehicle (EV) car charger. Of around 1000 new homes built in NSW in a year, more than half have had the solar and battery added - a “Solar ChargePack” offer. That is because more customers are opting to include energy security since the price of electricity in Australia is high and rising.

The Solar ChargePack includes 5.4kW of rooftop solar and a Tesla Powerwall 2 battery with 13.5kWh of electricity storage. They are even offering the chance to win a Tesla Model S EV as an incentive!
