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.
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.
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.
So, what is so great about these batteries anyway? Well here are the "Pros" for Lithium & Lead Acid so you will understand where all this is going.
Why aren't more Federal Buildings covered with solar panels?
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.
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.
From business to government to schools, wind power is creating new opportunities.
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.
A new type of environmentalist is emerging, using nanotechnology based products as a way of reducing their impact on the environment and reducing their energy use in a variety of ways.
If you are a building owner that is considering a solar panel installation, there are several questions you should ask before signing any contracts. What is the best mounting method for installation on my rooftop? Do I need a new warranty to protect myself from any damage? Which type of system will give me the best ROI? Do I work with my old roofing company or do I need to find a structural engineer?
Altenergymag interview with Barry Kay, President of Kay + Sons, a national leader and expert in how light is managed in buildings of the future.
Though North America lags Europe on the wind energy front, with less cumulative installed capacity despite a vast geographical size difference, growth is strong and has only scratched the surface. Huge potential, particularly, exists in offshore installations, which represent just a small percentage of global wind capacity to date. Ocean-based turbines, both floating and fixed, take advantage of powerful, more consistent wind speeds and a topography that doesn't obstruct wind flow.
Many people mistakenly buy larger air conditioning units than they need because they believe that a larger unit will both operate and cool their house more efficiently. In truth, a larger unit could be less efficient.
Foundations are critical to the success of a wind turbine project, and since foundation types are as varied as the earth conditions and types of structures being supported, we examine below some of the considerations involved in foundation selection such as siting, cost, and geotechnology.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
