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.
Project of the Day—Blue Freedom is the world’s smallest hydropower plant. It’s portable, which means you can bring it to areas where there isn’t any electricity at all and, a long as you’ve got access to running water, you can power a number of devices for hours on end.
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.
Four local companies have acquired 22 struggling power plants in a
massive public auction. Under the deal, the micro-dams will be managed
by new owners for the next 25 years, KT Press has learnt.
The new buyers include four individual local companies and ten other
companies in joint ventures between local and international firms.
Ngali Energy Ltd. acquired Base I and II, Ngororero, Rwondo and
Ntaruka III while Rwanda Mountain Tea purchased Gihira and Rugezi Power
plants. Rural Energy Promotion Ltd acquired Mutobo plant and Prime
Energy Ltd purchased Rukarara 6.
Under the deal, the companies are obliged to commit to rehabilitation
and upgrading the dams to ensure sustainable power production.
The government committed purchasing the power generated. The partners
have also signed a 50% revenue sharing agreement, after calculating the

Drop-in-stream pumps require minimal upfront installation. This river pump from Rife Hydraulic Engine Mfg. can lift water up to 82 feet vertically without using electricity or fuel.

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.
