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.
Is Lithium the new "Holy Grail" in Battery development?
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.
Solar Federal Buildings Program
Why aren't more Federal Buildings covered with solar panels?
Global Biodiesel Market Analysis and Forecasts to 2020
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.
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?
Total Light Management To Save Energy
Altenergymag interview with Barry Kay, President of Kay + Sons, a national leader and expert in how light is managed in buildings of the future.
Sea Change: Recommendations For Offshore Wind Farms
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.
What Size Air Conditioner Do I Need?
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.
In Support of Wind Energy: The Foundations that Underlie Wind Projects
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 Solar Industry: Where it has been, where it is now and where it has to go
The average solar stock has moved up 124% since March 9th 2009 and the average gain for just the 8 Chinese based public solar companies ( CSIG,CSUN,JASO,LDK,SOLF,STP,TSL,YGE ) was an amazing 267.96% !
