Investments in new clean-energy capacity will total $1.61 trillion through 2020 even as the expansion of renewables is expected to slow, the International Energy Agency said.

California and Quebec, which together created the largest carbon market in North America this year, may come away empty-handed as they woo northeastern U.S. states to join their system.

Europe’s concern about its reliance on Russian fossil fuels may spur governments to prioritize alternative energy, the head of Neste Oil Oyj said.

The downfall of two leading marine- energy developers is damping hope that the emerging industry, which has already lost almost $1 billion, will ever get the technology to market.

Japan’s trade ministry is setting stricter rules for production and sales of renewable energy in what it says is a drive to speed up development of projects and ensure stable power supply.

Spending on renewable energy, which surged 16 percent in 2014, will remain strong this year, largely unaffected by the slumping oil prices that have artificially depressed their shares.

Sweden and Norway agreed to boost their target for renewable energy production amid concerns the additional capacity will exacerbate a power glut and strain the region’s electricity grid.

The U.K. company planning the world’s first tidal-lagoon power station said its next plant may generate electricity at almost half the price.

Investors have spent more than $2 trillion on clean-energy plants in the past decade and last year added more renewable capacity than ever before.

Alternative energy mutual funds are continuing to recover from a slump which started in fall 2014. Annual returns range greatly, though, from a high of 15.6 percent for Brown Advisory Sustainable Growth (BIAWX), to a low of -15.8 percent for Guinness Atkinson Alternative Energy (GAAEX). The large 12-month drop by GAAEX was precipitated by painful losses in some of its top weighted holdings.

Hydraulic fracturing, or fracking, is shunned by the environmentalists that laud renewable energy sources. However, by not supporting both initiatives, they may be working at cross purposes. Natural gas, booming largely because of fracking, complements renewable energies on the grid. The two seemingly opposite technologies are, for the moment, inextricably linked.

Trillions of dollars will be invested in renewable energy over the next 25 years, driving some of the most profound changes yet in how humans get their electricity. That's according to a new forecast by Bloomberg New Energy Finance that plots out global power markets to 2040. 

More than a year after Prime Minister David Cameron publicly announced support for the Perpetuus Tidal Energy Center (PTEC), Great Britain’s Marine Management Organization (MMO) issued a license on April 20 to Royal HaskoningDHV to deploy and operate a proposed 30-MW tidal array at the center, located off the Isle of Wight.
