Move over, corn and soybeans: The next biofuel source could be giant sea kelp

Making biofuels from crops grown on land poses trade-offs between food and fuel. A new study looks offshore.
The New Zealand government is introducing legislation to become zero-carbon by 2050, but will consider new permits for coal mining, offshore oil drilling and fracking on a case-by-case basis. from shutter

Why New Zealand should not explore for more natural gas reserves

Natural gas is touted as a “bridging fuel” to displace coal while moving to a low-carbon economy. In New Zealand, this is shortsighted and could lead to stranded assets and hold back renewables.

Sydney’s closer to being a zero-carbon city than you think

Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney’s backyard add up to a zero-carbon energy solution for the city.
A medium-size passenger jet burns roughly 750 gallons of fuel per hour.

Jet fuel from sugarcane? It’s not a flight of fancy

Scientists have engineered sugarcane to increase its oil content and are developing renewable jet aircraft fuel from the oil. The engineered sugarcane could become a valuable energy crop.
Polysaccharide molecules such as cellulose, seen here, are long chains of sugars that are very hard to break apart. Enzymes – proteins that can degrade polysaccharides – have many industrial uses. CeresVesta/Wikipedia

Scientist at work: Bio-prospecting for better enzymes

Bio-prospecting is the search for useful materials from natural sources. A biologist explains what we can learn from bacteria about breaking down plant material, and how we can use that knowledge.
