    Getting off gas not so easy for renters

    Standard electric heaters turn roughly one unit of electricity into one unit of heat. A reverse cycle air conditioner, however, uses electricity to 'pump' heat from one place to another and is incredibly efficient. Using electricity from the grid creates more pollution than burning gas, but the electric reverse cycle air conditioner is so efficient it's still less damaging overall. That's great news for households with air con, but galling for anyone who can't afford one, or isn't allowed to install it.

    Egypt and Ethiopia river wars be dammed

    The building of the Grand Ethiopian Renaissance Dam on the Blue Nile by a major Italian construction company remains a source of tension between Ethiopia and Egypt. Egypt sees the Nile as its sole source for the survival of its population and, historically, has seen itself as its sole natural guardian. Ethiopia argued in response, on the basis of unseen studies, that there would be no reduction of water downstream. Both are mindful of the disastrous war they waged against each other early in the 19th century.

    Repeat your name over and over and it doesn't make sense. Being able to hear your name across a noisy crowded room. Being able to see things in the dark by not looking at them directly. Walking down an old path brings back a conversation you had in exactly the same location years ago. Your handwriting looks exactly like your father's. Revisiting a childhood park destroys the memory and paves over it with the newer, boring adult memory. When you chase something you can't have it.

    Waiting for the trickle down effect

    In an age of 'budget repair', social policy risks becoming just a sidebar to economic policy which is a contest of ideas about how best to grow the size of the pie thereby providing a slice for 'the deserving poor' without having to redistribute too much of the pie, while 'the undeserving poor' drop off the edge as they would have anyway. For those of us schooled in Catholic social teaching, the so-called 'undeserving poor' are the litmus test of our commitment to the human dignity of all persons.

    Racism and renewables in the developing world

    A 2015 cartoon by Bill Leak depicts an Indian family squatting, smashing solar panels to pieces. A woman chews on a shattered piece of glass, and a man attempts to smear mango chutney onto glistening shards. The initial reaction centred around the racist depictions of Indians. But it also represents a broader and worrisome attitude towards global energy politics, that assumes idiocy in developing countries, combined with a push to burden them with the dangerous wares of a dying industry.

    Climate pipe dreams

    About 40km from Warrnambool in south-western Victoria is Australia's first demonstration site for storing carbon dioxide pollution deep underground. In photos, it doesn't look like much - a few water tanks, sheds and pipes in a brown paddock - and yet plans to meet the internationally agreed climate change target are betting on the success of projects like this. This isn't a fringe strategy anymore. It is a big part of the mainstream, politically preferred approach to address global warming.

    Earlier this month Tesla launched the Powerwall 2. In the transition to renewable energy, it may be the biggest disruption to hit traditional energy companies yet. In fact, it's probably their worst nightmare. Our role in energy under this innovation has changed from us being consumers to possibly all being providers. Just as Uber disrupted taxis and Airbnb disrupted traditional hotel chains, so too will the Tesla battery change our relationships and transactions with energy.

    Pain is a cold food like garbage left, no compassion ... Compassion, bread and old wine, waste in a temple to worship money and power. Mankind has lost its root system thirst for happiness. Our bread is autumn leaf tossed into the branches as the bird dies. They make wine from the waters of these rivers suffering bloodied by the blood of Syrian children. Wine is the blood of indifference on the streets of Palestine. The wine is the blood of cruelty in Nauru ... why are you silent?

    No rest for Borneo's indigenous rights warriors

    One year ago, a remarkable win for indigenous rights took place in a little-reported corner of Asia. On the island of Borneo, rainforest communities won a long fight against a hydroelectric dam that was to be built on their land. After more than two years of muddy resistance, the dam plans were shelved, and land rights were restored to the indigenous population. This was a landmark win, in more ways than one.

    Turnbull's coal pitch is a Trojan Horse for gas

    Australia's most politically contentious rock is back in the limelight after Prime Minister Turnbull spruiked 'clean coal' power stations in early February, and Scott Morrison brought a lump of the stuff to parliament. It was a juvenile act, but an effective one: here we are again, still talking about coal weeks later, when the real energy policy battle is over gas. But that's how it goes - a pitch for a new coal-fired power station in Australia is actually a clever exercise in repositioning gas as a greener fuel.

    Financial literacy programs need to get real

    Studies have found that in Australia, groups with the poorest financial awareness and skills are those under 25, those with no formal post-secondary education, those on low incomes and working 'blue collar occupations', and women. While it makes sense to provide these groups with financial information on home loans and super, this wouldn't have helped my mother when she had to decide between, say, buying groceries for the week or getting the car serviced.

    Bond notes bode ill for Zimbabwe's currency calamity

    Last week, the much dreaded bond notes were released into the economy, in a move hoped to alleviate the cash crisis. Most citizens are negative about the move, with good reason - the last time Zimbabwe had its own currency was 2009, when inflation was so high the currency had to be dropped to salvage the economy. Most Zimbabweans remember that time well: every other month citizens had to drive to Botswana to put food on the table because the country's own shops were empty.
