Urban Green Energy is a world leader in small wind energy, focused on providing high quality, high performance, and attractive products to customers around the world. UGE's products include vertical axis wind turbines and hybrid streetlamps.
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.
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.
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?

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
