Clean Energy Transition

A few good points. And whether we agree on climate science or not, the scientific debate should remain open and serene. In the end, there will always remain a degree of uncertainty, and the decision to act, and to what extent, becomes then a political choice.

"DSIRE is a comprehensive source of information on state, local, utility, and federal incentives and policies that promote renewable energy and energy efficiency. Established in 1995 and funded by the U.S. Department of Energy, DSIRE is an ongoing project of the N.C. Solar Center and the Interstate Renewable Energy Council."

Australia's first community wind farm.

The parameters for this project are interesting. The biggest challenge for these cooperatives is to scale up to finance larger projects. The fact that this group raised almost 10 M$ is encouraging.

Interesting that EWEA develops this kind of tool.

What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap."

The Fraunhofer Institute is using a redox flow battery, a type of cell that uses two electrolytic fluids exchanging protons through a membrane. This process generates electricity. Although this type of battery isn't new, the Fraunhofer Institute improved the energy density, making it equivalent to that of a lithium ion battery.

A similar conclusion was reached by a UK Automotive sector report for UK Govt in support of the Low Carbon Transition Plan published last year.

"Rwanda harnesses volcanic gases from depths of Lake Kivu Project could power Rwanda for decades, while reducing risk of disaster for 2 million people living alongside 'exploding lake'"

Good catch Phil. We like to see things in this group which are the first deployment of a new concept, pushing the boundary for sustainable energy.

"Mission: To promote the implementation of anhydrous ammonia as an affordable, sustainable, carbon-free fuel for transportation and stationary power applications, thereby enhancing economic security, reducing fossil-fuel dependence, and helping save the environment. Anhydrous ammonia is an ultra-clean, energy-dense alternative liquid fuel. Ammonia is the only fuel other than hydrogen that produces no greenhouse gases (GHG) on combustion. Ammonia will power diesel and spark-ignited internal combustion engines, direct ammonia fuel cells, and even combustion turbines. And, ammonia can be manufactured from simply water and air using clean renewable energy."

**Extremely useful comparison + charts** Covers 11 technologies from 6 data sources. Source detail included in appendix. Costs: capital, fixed, operating, learning factor; Technical: size, heat rate, [potential] capacity factor, service life. Note on unit life: not all data sets include this, some run as long as plant is economic (no pre-determined retirement age), can represent max service life or is just used to compute economics (e.g. LCOE).

Recently, the District of Columbia became one of the first government organizations in history to publicly promote its system-wide efficiency. The District started to invest in measures to better understand its use of energy throughout its almost 200 public buildings. By energy benchmarking, it hopes to cut back on its use of electricity, natural gas, and other fuels and consequently reduce its greenhouse gas emissions.

"China, the world leader in wind power by installed capacity, is facing a growing problem with grid connection as more than half of the electricity its wind farms generate goes unused."

Good catch. Such lack of coordinated planning is not unusual in a start-up, but let's hope it will be just that - a temporary mismatch in the synchronisation of planning 2 major infrastructure projects (wind power generation & transmission networks).

This Biolamp is designed in order to convert the CO2 into fuel that can generate the street lamp in entire city road

This latest technology was unveiled during Yokohama Renewable Energy Exhibition 2010 and has proved that it is the most innovative and successful technology for wind turbine
