Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

The United States got the Grand Coulee on the Columbia River, the Hoover Dam on the Colorado, and the dams of the Tennessee Valley Authority. Instead, that pure status is now reserved above all for wind and solar. The manufacture of solar panels involves the environmental costs from mining, waste disposal, and carbon emissions.

DOE to award $35M to 24 projects to support early-stage, innovative technologies and solutions in advanced manufacturing

Green Car Congress

Colorado State University. Colorado State University will develop a novel, low-cost turbo-compression cooling system that utilizes the ultra-low-grade waste (less than 150°C) heat available in many industrial processes, the energy from which is not traditionally recovered. Dana-Farber Cancer Institute. Idaho National Laboratory.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) That’s why Liu’s Thermal Energy Storage Group at ORNL is focused primarily on buildings.

IEA: Estonia is pioneering technologies for more efficient and cleaner use of oil shale

Green Car Congress

Waste heat is used to generate electricity, making Enefit shale oil plants net producers of electricity. The US tops the list of the richest oil shale reserves, accounting for more than 60% globally, with the most concentrated deposits located in the Green River Formation that lies in western Colorado, eastern Utah and southern Wyoming.

Study: new international agreements needed to ensure sustainable supply of minerals and metals for low-carbon energy tech

Green Car Congress

Climate change mitigation will create new natural resource and supply chain opportunities and dilemmas, because substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure.
