Commentary from Industry Pros
Each month my wife and I have to pay the electric bill for our home. I was wondering why haven't the residential building companies that build houses, apartments, townhouses, and condos all come to a general consensus, and decide to make all everything that they build solar powered?
In a state long-associated with oil ("Texas tea") and conservative politics, you would think renewables would have a hard time getting a toehold.
In recent years, several inventive entrepreneurial types have challenged the theory of the 2 and 3-bladed horizontal-axial axis wind turbine, claiming that the space between the blades has been wasted and could be used to generate additional output. Many of them have actually built and tested small-scale prototypes to prove their point.
When comparing clean energy systems for generating electric power, technology evaluation is dependent on understanding resistance, current, and voltage factors.
Low-cost, zero-emission wind energy will become even more valuable as states and utilities develop plans to cost-effectively reduce carbon pollution to comply with EPA's Clean Power Plan, according to new economic analysis from the Energy Information Administration (EIA), a nonpartisan branch of the Department of Energy (DOE).
Solar energy is an economic boom for North Carolina. Only California installed more solar in 2014, pushing the Tar Heel State to fourth overall in America with 953 megawatts installed capacity - roughly the electricity demand of 90,500 homes.
The thin film solar cell industry in transition: knockout phase is over - profitability and vertical integration nextPrices of solar cells and solar panels have fallen dramatically over the last few years. This (and state subsidies) has been good for the advancement of this amazing renewable energy source, and solar energy can today be seen as an established energy source, reliable and well distributed, cost competitive with traditional non-renewable energy sources and with a very healthy annual growth in installed solar panels.
Solar energy is a booming business across North America. Installations grew 30 percent across the United States in 2014 for the industry’s biggest year yet, but industry expansion also brings consolidation – Ernst & Young reports industry deal values hit a four-year high of $177.1 billion in 2014, with investment and acquisitions both predicted to keep rising in 2015.
EPA Administrator Gina McCarthy has been saying repeatedly that the EPA's Clean Power Plan to limit carbon emissions from coal-fired power plants give states flexibility.
In the current Supreme Court case known as State of Michigan v. Environmental Protection Agency (EPA), Michigan and 22 other states have sued the EPA over new regulations that were designed to further reduce the level of mercury, arsenic and acid gases emitted by power plants.
