Micro Inverter or the AC-Module Inverter: Truths vs. Myths
When it's time to choose an inverter for a PV system, the system owner and the
installer have the choice to use a string inverter or micro inverters for the installation. It is
important to realistically assess the viability of this technology.
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.
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.

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.
Wind Power is Going to the Big City
From business to government to schools, wind power is creating new opportunities.
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.
NanoPioneers Are Becoming the New Environmentalists
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.
What Building Owners Need to Know Before Going Solar
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?

Featured Product
Roof Tech - E Mount AIR
The most compact versatile rail-less PV mounting system under the sun. Instead of placing solar panels on top of long rails, simply attach E Mount AIR to rafters or the roof decking. Once panels are fastened to the roof, the system array is electrically bonded. The result is a visually seamless PV installation that stands the test of time. - Truly "One With The Roof". - PE stamped cert. letters available, UL 2703 Classified, ASTM 2140 fully waterproof.
The one and only with integrated flexible flashing certified by the ICC!
All the best quality. Only from Roof Tech
