Fully renewable electricity could be competitive

(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.

Cold cities less sustainable than warm cities, research suggests

(Phys.org) —Living in colder climates in the US is more energy demanding than living in warmer climates. This is according to Dr Michael Sivak at the University of Michigan, who has published new research today, 28 March, ...

Harvesting unused energy with flat thermoelectrics

A large proportion of the energy we produce disappears unused into thin air via waste heat. Tiny thermoelectric generators can tap this potential, whereby the electricity is produced by way of temperature differences. However, ...

Using fluctuating wind power

Incorporating wind power into existing power grids is challenging because fluctuating wind speed and direction means turbines generate power inconsistently. Coupled with customers' varying power demand, many wind-farm managers ...

Development of handy fuel cell system

Researchers at AIST, Japan, have developed a handy, portable fuel cell system. While the developed system employs microtubular solid oxide fuel cells (microtubular SOFCs), a nanostructure-controlled electrode has enabled ...
