The political dilemma over geoengineering – deliberate, large-scale intervention in the climate system designed to counter global warming or offset some of its effects – will perhaps be most acute in China.
In December, the country listed geoengineering among its Earth science research priorities, in a marked shift in the international climate change landscape noticed by China specialists Kingsley Edney and Jonathan Symons.
Mecca, which hosts millions of pilgrims a year visiting Islam's most holy shrine, is working toward becoming the first city in Saudi Arabia to operate a utility-scale plant generating electricity from renewables.
ACEEE has just released a series of six profiles of real world experiences in energy efficiency job creation. These profiles describe programs, policies, investments, partnerships, and business models that have catalyzed regional increases in employment. While previous ACEEE work has provided an analytic framework for how jobs are created through efficiency, this paper focuses on the jobs themselves.
In August 2012 DENA has published a third study on the integration of renewables in Germany. The study was made in cooperation with Aachen University.
It is the purpose of the study to analyse how the political targets will change the electricity supply system by 2050 and to identify infrastructure challenges. The study is mainly based on the Guiding Scenario 2009, published by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). The Guiding Scenario 2010 was not yet published when DENA began working on the integration study.
Did you read this article in Bloomberg about how rooftop solar is costing California ratepayers billions!!!!??? Then you should know it’s largely horsemalarkey.
What the article doesn’t say is how the utilities arrive at their figures–but based on previous assertions, we think it’s safe to assume the approach is grievously flawed. Let’s take a look behind utilities’ net metering ‘math’:
No portion of the electric power grid has been impacted more by grid modernization (that is, the “smart grid”) than the electric distribution system. A central part of this transformation is the distribution management system (DMS), which integrates numerous remote monitoring and central control facilities with enterprise-level systems to optimize distribution system performance and accomplish a variety of business goals. At the same time, distributed energy resources are often connected to the grid at the distribution level, and distribution operational requirements are impacted by their presence. The power inverters that connect solar photovoltaic and battery resources to the grid are highly capable devices with advanced message processing and fast power control and nearly instant response to received commands and monitored conditions. This white paper describes ongoing research at the Electric Power Research Institute (EPRI) that is exploring various ways in which the DMS can use these resources more effectively and help in accomplishing the 21st century objectives of electric distribution utilities.
Expect opportunity to heighten in Massachusetts next year. A key state advisory council in November approved utility efficiency plans that total $2.01 billion for 2013-2015. The plans require approval by the state Department of Public Utilities. A decision is likely in early 2013.
The utilities expect the plans to save 3.7 million MWh of electricity, enough to power more than 500,000 households for one year. Money for the programs comes from a surcharge on utility bills and auction proceeds from the Regional Greenhouse Gas Initiative.
Alumnos y docentes del Club de Ciencias de Malvinas Argentinas desarrollaron un original dispositivo para almacenar la energía solar y utilizarla luego para cargar las baterías de una motocicleta eléctrica.
Fourteen California counties and 126 cities launched the nation’s largest PACE program, an innovative financing tool to help commercial property owners reduce their buildings’ energy and water use, under the auspices of California’s largest...
Over the past decade, efforts in environmental stewardship have increased exponentially. Now being green, clean, and using renewable and sustainable energy sources are ways of life. More and more organizations are bending to the demands for efficient and unpolluted products, leading to a surge in green technologies and sustainable farming techniques. Such awareness and effort is truly commendable and has sparked impressive energy projects all over the world: one of the most recent being David Green’s Ecoisland project on Britain’s Isle of Wight. Within the past year, the Ecoisland project has become world-renowned due to its goal to make the small island a self-sufficient haven of renewable energy by 2020. Such prowess and devotion to environmental health is truly a praiseworthy cause that deserves applause and recognition.
Why is Britain not better insulated against volatile energy prices? It's an issue much bigger than how we heat our homes. More than a decade ago, rising fuel prices triggered protests by truck drivers that revealed the fragile nature of the nation's infrastructure. The government and the protesters seemed equally stunned at the swiftness with which a blockade of a handful of fuel depots could interrupt so many vital supply lines and services.
The data included in our infographic is an average of our most recently tested appliances.
Our expert testers also identify the most efficient models on the market, which can save you significantly on running costs even against the average power consumption.
Electricity usage derived from product testing between 2011 and 2012. The infographic shows the hot water heater using the lion's share of the power. However this is based on electric hot water heaters using an off-peak rate. If you have solar, heat pump or high-efficiency gas, then your water heating costs are likely to be much lower.
As a general rule, the older your appliances are, the more likely they are to use more energy. For example in late-2009 over 50% of new TVs had an energy rating of less than 4 stars. By mid-2011 this number had dropped to less than 10%...
by Justin Guay A few months back, Nancy Wimmer told us about Bangladesh’s solar success. In one of the poorest countries on earth, a renewable energy company, Grameen Shakti, is busy installing nearly 1,000 solar home systems each day.
There is much meaning behind the name Community Power. It does not only refer to electrical power generated by a community; it also implies individual and community empowerment.
Community Power enables individuals to take steps towards the betterment of the environment, their communities, and also their personal finances. It also enables these individuals to gather for a common purpose and achieve something extraordinary, as a community. This is where true economic, environmental and social sustainability lies. Through igniting individual behaviour change and community solidarity, Community Power starts an empowering process that enables communities to provide local solutions to their local needs for the long term.
Cerca de la mitad de las empresas de energías renovables de China ven con optimismo 2013 y esperan que su mercado nacional mantenga un rápido crecimiento ese año, aunque otro 9 por ciento de ellas teme encontrar cuellos de botella financieros,...
