The Big Dish, developed in Canberra, could be a renewable energy winner if the government focussed funding. WizardPower

Time for government to pick a renewable energy winner

Let’s start with a question: why has Denmark been so successful in renewable energy creation and uptake? It can’t be that Denmark is a windy place (although that helped) or that it was a social democratic…
ANU’s “big dish” solar is the envy of Asia, but the Australian Government has turned its back. AAP

Wake up Australia, and take a lesson on solar from Korea

I am here in Seoul, the burgeoning and confident capital of a burgeoning and confident Korea, to investigate the country’s formidable “Green Growth” strategy. Back in August 2008, the Korean government…
Cheap carbon nanotubes could be sprayed onto the windows of high-rise buildings, creating solar cells that generate power. Freefoto/Ian Britton

Solar technology could transform office blocks into power producers

Skyscrapers could one day generate enough power to offset much of their energy consumption, thanks to a breakthrough by Australian…
US-China competition could lead to a brighter clean energy future, or a trade war. whitehouse.gov

Who owns the sun? Patent law and clean energy

There is a trade war brewing between the United States and China over intellectual property relating to clean technologies – particularly solar power. Steven Chu, a scientist, Nobel Laureate in Physics…
Domestic solar panel use has risen dramatically in recent years; commercial uptake can’t be far behind. EPA/Patrick Pleul

We’re set to hit our renewable energy targets – now let’s aim higher

A recent report by the Clean Energy Council claims that the capacity of domestic solar panels in Australia has increased 35-fold in the past three years. This (among other factors) means we are well on…
India’s power needs are growing at a staggering rate and coal won’t do the job. NASA

How do you power a billion lives?

As the Australian Labor Party changes its stance on trading uranium with India, a pertinent question arises: why is India so keen to buy this controversial fuel? And what do India’s energy resources look…

City shadows reveal its energy flow

By calculating the amount of solar radiation reaching streets and buildings, researchers could help optimise the way energy…
Photosynthesis converts low-energy photons into usable energy; it may teach us how to do the same. papalars

New chlorophyll could hold the key to more efficient solar panels

As the great spectre of climate change continues to loom large over the future, the search for viable, renewable energy sources is becoming ever more important. Solar power has long been seen as a vital…
Building and racing a solar car is a true team effort. Matt Cumming

A first-hand account of the World Solar Challenge

The World Solar Challenge (WSC) is a race held every two years in which roughly 40 teams race solar-powered cars from Darwin to Adelaide. I’m a member of the UNSW Solar Racing Team (called Sunswift). The…

The World Solar Challenge and the future of solar cars

On October 20 2011, the Tokai Challenger solar car drove quietly into Victoria Square in the centre of Adelaide, winning the 2011 World Solar Challenge. The car had crossed Australia from north to south…
There are several options for future energy generation. We just need to get there. waldopepper

Stepping stones: the slippery path to a clean energy future

In news today, the Greens are calling for an end to federal funding for a proposed coal- and gas-fuelled power plant in Victoria’s Latrobe Valley. Others have suggested the plant provides a source of “transition…

Solar will force coal and nuclear out of the energy business

A solar energy revolution is brewing that will put the coal and nuclear industries out of business. Solar is already reaching price parity with coal in many parts of Australia. In contrast to coal and…
Concentrating solar energy has a lot of commercial potential in Australia. John Marmaras/CSIRO

With a bit of concentration, solar thermal could power your town

Most people are familiar with solar energy generated by photovoltaic (PV) solar cells; they are the tiny PV cells on your calculator or the large PV installations that many people are installing on their…

Wild is the (solar) wind

Satellite observations have revealed that magnetic oscillations carrying energy from the Sun’s surface into its outer atmosphere…
