Solar, just like all renewable power-technologies, has the constant challenge of price competiveness with fossil fuel electrical production. These traditional sources of electricity (by far and away) lead the market place, with emerging technologies struggling in their attempts to drive their costs down, and output efficiency up. Solar power production is the only emerging technology [...]

NUCLEAR POWER PLANT UPDATE
Consider this: Almost all of our nation’s 104 nuclear power plants were built between 1969 and 1996, and all were online by the year 2000. Which is pretty astounding considering that each plant is required to be licensed for 40 years of operation. The reason being, they represent 20% of the United States’ power generation. Therefore, with the [...]
FUNDING ENERGY-SAVING PROJECTS
Conversion of a company’s lighting systems (or their means of receiving power) can have large up-front costs. Going Green with solar, wind turbine, biomass generation, etc., may save you money in the long run, and it certainly offers more environmental conscience to your company, but the initial investments may still be financially consuming. As an [...]
THE BUSINESS OF GOING GREEN
Driven by unstable fuel prices, increased energy consumption and government regulation, the business of going green is soaring. The Energy Independence and Security Act has set in motion green building technology implementation in federal buildings. The bill includes provisions to improve energy efficiency in lighting, appliances, and equipment. At the same time it pushes for [...]
SOLAR COSTS FALLING
A September 2011 report from the US Department of Energy (through its Lawrence Livermore National Laboratory) states: “The cost to install a photovoltaic system (solar collection and electrical power conversion) has fallen by 17% or $1.30 per watt, from 2009 to 2010, with similar results from January through June 2011.” Factors are: A drop in [...]
ELECTRICITY’S EFFECT ON OUR LIVES
We take for granted the greatest physical force ever harnessed to increase our comfort, productivity, quality of life and financial well-being, electricity. The huge benefits of electricity are with us constantly. We just assume that when we need it, that it will always be there. We don’t think or even care where it comes [...]
LED, PROS AND CONS
ADVANTAGES OF LED LIGHTING Some advantages of LED lighting over conventional lighting sources: Lifetime LED lights can last from 30,000 – 75,000 hours (50,000 hours is the average) depending upon the quality, durability and use of the fixtures. With an average use of 6.5 hours per day, this can amount to over 21 years of [...]
LED, WHAT IS IT?
Light Emitting Diode (LED) is a semiconductor light-producing unit. When an electrical current passes through the unique materials, there is a recombination of positive and negative charges resulting in the emission of photons, as light energy. This action is called electroluminescence. The color of the light is determined by the energy gap of semiconductor and [...]
GREEN EFFICIENCY
Our power needs will always require changing technologies and long-range thinking, but at the same time we must develop new strategies to save energy, helping us to move toward energy sustainability. The supply and demand sides of our energy equation are both keys to our future electrical needs. Technological development in the following areas are [...]
FIRST-GENERATION GREEN TECHNOLOGIES
HYDROELECTRIC Hydroelectric power plants have been in existence over 100 years. They are considered a clean, renewable energy technology with few emissions. Although considered “Green” by most definitions, hydroelectric dams are criticized for the large CO2 amounts produced during construction, as well as the displacement of people and loss of land and vegetation, due to [...]
