One of the key problems with renewables is their intermittent availability. You can only generate energy from the wind when it is blowing, or from the sun when it's shining. Critics argue this is why we will never be able to rely on renewables for the majority of our electricity generation. But that criticism may soon be silenced.

THE price of a cup of coffee. That's one estimate of what it will cost each American every day for the next 20 years to break the fossil fuel habit of generations and turn to renewables instead. A daily outlay of a shade under a couple of dollars does add up to trillions over the decades, but is it really that much to ask? (Editorial)

At first glance, geothermal energy seems almost too good to be true. It's clean, inexhaustible, provides predictable 24-hour power and you can get it just about anywhere. There is a snag, however. Outside of geologically blessed places like Iceland, Japan and New Zealand, where volcanically active rocks are close to the surface, the Earth's heat is locked away under several kilometres of rock.

Wave power generation cum shore protection project envisages tapping the energy of ocean waves and wind for the generation of electricity and integrating it with the national power grid. A number of impellors are arranged parallel to the shore for a span of 500 m at a distance of about 100 m from the seashore. Impellers are designed to tap the trienergies of ocean waves.

With the average price of a gallon of gasoline hovering somewhere around $4 in the U.S. and oil prices continuing to rise the whole world is refocusing their attention on the viability of alternative energy sources. A window seems to be opening for genuine progress in lessening our dependence on fossil fuels.

The EU has assumed ambitious targets and strategies for the promotion of renewable sources of energy (RES) binding to all its member states. This report examines the proposed EU-wide policy instrument designed to help achieve the targets on renewable electricity and heat - the trading of Guarantees of Origin

Climate change represents one of the humanity

Australia will set up a A$100 million (US$80 mln) carbon capture research institute aimed at fighting climate shift and with ambitions of becoming the world hub for the technology, the government said on Friday.

The Ladakh Ecological Development Group or LEDeG for short is an NGO (non-governmental organization), which came into being in 1983, and has been actively involved in awareness generation programmes related to the environment and sustainable development. LEDeG is a firm believer in being a real practitioner of alternate energy technologies like solar PV (photovoltaic).
