Renewable energy had its best year yet

A new report has found that renewable energy power capacity around the world grew more in 2015 than in any other year in  history. A majority of the new additions to sources of renewable energy in the power sector came through wind, solar and hydropower. And that’s good news for those down on their luck.

The costs of growing populations. One of the toughest environmental arguments to make. Do you side with 23 million people who need electricity, or do you side with 20,000 indigenous people and a sliver of the Amazon rainforest and all its riches? Should they turn to nuclear power, and if so, how to pay for, monitor, and maintain it?

The proposed Belo Monte Dam in northern Brazil would be the third largest hydro-electric dam in the world in terms of electrical output. The dam would be 3.75 miles long and generate over 11,000 megawatts, which could power up to 23 million homes. Government officials say that the dam is an essential step in supplying energy to the nation’s growing population. However, the project is rife with environmental conflicts. The project requires the clearing of 588 acres of Amazon jungle, the displacement of over 20,000 indigenous people, flooding a 193 square mile area, and drying up a 62 mile stretch of the Xingu River.

A former pump house in Lake St Clair, Tasmania, turned into a guest house.

The three-storey concrete building at the end of a jetty was a turbine house used when Tasmania embarked on a hydro-electric power experiment in the 1940s, but was later abandoned and has been sat unused for over 20 years. The building, renovated by Cumulus Studio now incorporates 12 guest suites.
