Case Study - Western Reserve Wind Project

The leadership of Western Reserve Local Schools should be applauded for installing a wind project that allows them to be fiscally responsible, climatically aware and educationally adaptive.

AltEnergyMag Interview - Geothermal Heating and Cooling

ENRGi was formed to bring the energy and costs savings of geothermal heating and cooling to residential and commercial buildings in the northern New Jersey area. Unlike most contractors that can install this equipment, we focus solely on geothermal environmental controls. In addition to having certification from the IGSHPA (International Ground Source Heat Pump Association), ENRGi also hosts educational seminars on the benefits of geothermal technology for the public.

AltEnergyMag Interview -Thermal and Hybrid Solar Collectors

With the Volther Solar hybrid collector, production of both electricity and hot water is done simultaneously. In PV modules, as the module temperature increases, the efficiency of the module drops down. In hybrid modules, the module heat is absorbed in order to produce hot water. In this way, PV efficiency is optimized as the heat is transferred into water for hot water production.

Google Invests $38.8 Million in Wind Farm

It is the first of its kind for Google and the company may use the extra energy to power, at least partially, its many data centers. “On Friday we made our first direct investment in a utility-scale renewable energy project — two wind farms that generate 169.5 megawatts of power, enough to power more than 55,000 homes,” Rick Needham, Green Business operations manager at Google, wrote. “These wind farms, developed by NextEra Energy Resources, harness power from one of the world’s richest wind resources in the North Dakota plains and use existing transmission capacity to deliver clean energy to the region, reducing the use of fossil fuels. Through this $38.8 million investment, we’re aiming to accelerate the deployment of renewable energy — in a way that makes good business sense, too,” he added.

Global Investments in Renewable Energy are expected to reach $653.35 billion by 2015

Technological innovations are underway to make these sources more affordable and efficient, which will result in their wider application. Thus, technological innovations and research and development activities for renewable energy are gathering momentum.

Durathon™ Battery for Utilities from GE

GE Energy Storage Technologies, a unit of GE Transportation unveiled today its Durathon battery technology for utility companies. As power consumption continues to grow, infrastructure ages, and new elements evolve such as renewables and electric vehicles, the grid is being asked to perform as never before. GE's Durathon battery technology offers an intelligent way to approach these issues. As part of a simple energy storage system, GE's Durathon battery provides an alternative to costly new power structures, which enables energy to be utilized when it's needed. Because of its proprietary chemistry, the Durathon battery has the ability to last up to two decades while providing optimal charge and discharge times. Durathon batteries are well suited for applications in extreme temperature environments because the need for an expensive controlled environment is not required to deliver peak performance. This minimizes installation costs along with the batteries high energy density.

Most Chinese prefer alternative-energy vehicles

Nearly 60 percent of Chinese consumers will consider purchasing plug-in hybrid vehicles or electric vehicles, according to a survey released by Ernst & Young Global Automotive Center on Thursday. This figure is five times higher than that of other countries, such as the United States, Japan, Germany, the United Kingdom, Italy and France. One reason why Chinese consumers choose alternative-energy vehicles is they have a better understanding of them. The other reason is that Chinese tend to have a short commute, which is compatible with the short battery life of alternative-energy vehicles.

10 Green Giants That Could Change the World

While start-ups have played a crucial role in getting the green industry off the ground, the future will likely be dominated by large, sprawling conglomerates. Why? Green technology essentially involves revamping the physical infrastructure of the modern world: replacing coal-fired power plants with wind turbines, building homes from materials concocted in chemistry laboratories, and swapping out engines for electric motors. Established companies simply are in a far better position to muster the capital, technological depth, managerial expertise and factory capacity needed. Familiarity plays a big role too. Millions have flocked to play Farmville. You won't see the same sort of giddy enthusiasm for those installing high voltage power lines or sewage-to-drinking water plants. If the Internet boom was an under-30 billionaire, clean tech is a science teacher with a comb-over. With that in mind, here is my list of the top ten Green Giants, the companies most likely to produce, develop and promote the ideas an products that will have the widest ranging effects.

GlobalData's report, "Global Biodiesel Market Analysis and Forecasts to 2020", is an essential source of information and analysis on the global biodiesel market. This report gives an in-depth analysis of the global biodiesel market and provides forecasts up to 2020.

Renewable Energy Production from Tannery Wastes

The conventional leather tanning technology is highly polluting as it produces large amounts of organic and chemical pollutants. Wastes generated by the leather processing industries pose a major challenge to the environment. According to conservative estimates, about 600,000 tons per year of solid waste are generated worldwide by leather industry and approximately 40-50% of the hides are lost to shavings and trimmings. Everyday a huge quantity of solid waste, including trimmings of finished leather, shaving dusts, hair, fleshing, trimming of raw hides and skins, are being produced from the industries. Chromium, sulphur, oils and noxious gas (methane, ammonia, and hydrogen sulphide) are the elements of liquid, gas and solid waste of tannery industries.

The Science of Solar: Solar Energy - The Basics

Solar is one of the most talked-about alternative energy sources in the world today. Enough energy comes from the sun in one hour to power the global population for a year. Even though the amount of sunlight varies around the world, sunlight is a totally renewable resource, unlike oil, coal and natural gas. As long as life exists on the earth, sunlight will play a role.

Strong Solar Growth in 2009 Despite Recession

The Solar Energy Industries Association (SEIA) released the 2009 U.S. Solar Industry Year in Review, finding 2009 to be another year of strong growth despite the economic recession. Overall U.S. solar electric capacity, including both photovoltaic and concentrating solar power installations, increased by 37 percent. This was driven primarily by strong demand in the residential and utility-scale markets, state and federal policy advances and declining technology prices. As a result, total solar industry revenue reached $4 billion, a 36 percent increase over 2008.  The solar industry contributed to the overall economy by adding 17,000 new jobs from coast to coast. The solar industry today employs 46,000 U.S. workers and supports an additional 33,000 jobs in other sectors.
