A massive eight-year construction feat to bore a 41-foot-wide, 6.3-mile-long tunnel deep beneath hard rock under the City of Niagara Falls in Ontario, Canada, was successfully completed this March.

A 10-MW ocean thermal energy conversion (OTEC) pilot plant is being planned off the coast of southern China by global security and aerospace firm Lockheed Martin and Beijing-based cleantech firm the Reignwood Group.

Panelists at a House hearing today refuted varied claims concerning if and how increased natural gas and renewables generation pose widespread challenges to the reliability of the electric grid. Some pointed to ineffective rules in the restructured wholesale power market and the failure of conventional power plants as being more of a threat to grid reliability.

In a milestone for the fledgling marine power sector, Alstom’s 1-MW tidal turbine (Figure 6) generated power for the first time at the European Marine Energy Centre’s tidal test site in Orkney, Scotland.

Small-scale hydro generation stands to benefit from recent congressional action aimed at streamlining what historically has been a challenging federal approvals process. That action, along with technology innovations, could make it easier to develop hydro generating capacity in sources as diverse as navigable rivers, man-made conduits, and water distribution systems.

Public and private investment in solar, wind, and other renewables worldwide declined 11% in 2012 from an adjusted 2011 record of $302 billion, a new survey from Pew Charitable Trusts shows. Yet the global renewable sector still registered a record 88 GW of new nameplate capacity last year, and China reclaimed the lead in global renewables investments from the U.S., it says.

Bipartisan legislation introduced on Wednesday by a bicameral group of lawmakers seeks to give renewable energy project investors access to an existing corporate structure whose tax benefits are now only available to investors in fossil fuel–based energy projects.

The Federal Energy Regulatory Commission (FERC) and the U.S. Coast Guard within the U.S. Department of Homeland Security on Tuesday signed a memorandum of understanding (MOU) to cooperate with each other on the development of projects that generate power from waves, tides, ocean currents, and the flow of rivers. A group of bipartisan senators, meanwhile, introduced a companion bill to a recently passed House bill that seeks to expand hydropower in the U.S.

Energy demand in Mexico, according to the Secretary of Energy (SENER), will increase by approximately 4% each year for the next ten years, and with it the potential for private sector growth in the industry. Download the report.
