The New Freedom Tower is the building being erected at the site of the former One World Trade Center. It is being built with great technological advancements including those that are positive for the environment. Here are a few examples of green technologies that are being utilized.

Guest Post: How Our Government Is Supporting Green

Government subsidies help aid an industry when it is not progressing fast enough in the free market. Generally, when new technology becomes available like green energy, it can take a considerable period of time before prices decline enough to where consumers find the technology affordable. The free market just doesn’t work as fast as some governments would prefer, so they intervene, helping important technology like green energy until it becomes profitable for businesses quicker than it would through the free market.

Principal Solar Institute Publishes White Paper Outlining Industry’s Ratings System for Creating, Testing, Monitoring Solar PV Modules

Guided by an advisory board of academic experts and solar professionals, the PSI PV Module Rating is based on physical tests by independent laboratories such as TÜV Rheinland, but is presented as a single comparative number that can be used with circumstantial information such as deliverability, pricing and manufacturer reputation so that solar power plant designers, buyers and financiers have a consistent basis for choosing a particular PV module. The system empowers these decision-makers to make informed, intelligent comparisons and determinations when selecting PV modules.

SolarCity to Power 26 Los Angeles Unified School District Schools with Solar Energy

SolarCity today announced a 7.4-megawatt (MW) solar power project that will bring renewable energy to 26 Los Angeles Unified School District (LAUSD) schools. The project will bring immediate and long-term cost savings to the District and is expected to save more than $776,000 in their first year and more than $25 million over the next 20 years.

SolarCity Selected by KIUC to Build Hawaii Solar Facility on Grove Farm Land to Help Reduce Kaua’i’s Oil Dependency

Grove Farm, headquartered in Lihu’e, owns approximately 40,000 acres on Kauai, making it one of Kaua’i’s largest private landowners. In its transition from a sugar plantation to a community development and property management company, Grove Farm has remained focused on building a more sustainable island community.

Guest Post: Status Report for the Solar Industry in Britain

With the cost of solar power installations coming down, the ability to expand a solar infrastructure from experimental to more lasting energy production was stimulated in 2010 by government policies for feed-in tariffs. Feed-in tariffs for solar power effectively pay users and businesses a small amount for the energy they produce, and offer contractors long-term contracts on a guaranteed purchase basis over 25 years.

IKEA Plugs-In Georgia’s Largest Private Solar Rooftop Array on Savannah Distribution Center

“Installing solar panels atop this facility demonstrates that the company’s sustainable commitment extends beyond our stores into all facets of the retail operations,” said William Jackson, Savannah Distribution Center Manager. “This solar array will reduce significantly the carbon footprint and electricity costs of this facility. We appreciate the continued support of the Chatham County, Georgia Power, and Gehrlicher Solar, our partners in this project.”

Living Roofs Boost Solar Panel Performance

It also turns out that solar panels can benefit from green roofs. Solar cells tend to perform better and convert more sunlight into electricity under cool conditions. Heat is also generated as a result of solar radiation, which is why high-performing solar panels often have the need for extra cooling. If solar panels are positioned on top of a conventional roof that consists of gravel or bare waterproofing membrane, even more heat is generated.

Guest Post: An Insight into Geothermal Pumps

Geothermal power offers the best green deal for home heating currently. The power comes from a range of different underground sources, including shallow ground, warm underwater springs and liquefied rock in the form of magma that lies far beneath the earth’s crust.

The Tesla Supercharger Network Revealed

On September 24th, Tesla Motors revealed that it had been hiding a bit of a secret. It seems that the much anticipated network of Tesla electric car charging stations was not only designed and ready for construction, but a mini-network of an initial six stations was already operational in California, having been built in secret.

Guest Post: Why You Need A Solar Water Heater

When it comes to burden on the environment, traditional water heaters could have the biggest impact among sources that no one ever thinks about. Water heaters (gas, electric and tankless) actually produce as much, if not more, CO2 than your typical automobile. At nearly 6,400 kilowatt hours of electricity per year, the water heater produces about eight tons of carbon dioxide annually, which doubles that of the standard automobile.

Guest Post: Guide to Picking the Best Solar System Components

The choice of components is a critical one. If you pick the wrong pieces of equipment, you may encounter unexpected problems, such as premature failure of the components or a low efficiency of the panels themselves. A reliable system will lower your energy bills for years to come, even to the extent that you might make money selling the surplus power. A poorly constructed system will cost a small fortune, as you need constant repairs and replacements.

Plug-In Solar: Moveable Solar Power For Renters and Do-It-Yourselfers

Rapidly falling prices of solar electricity equipment mean that the most costly part of installing residential solar power systems will soon be system design and installation. A new line of plug-in solar power equipment made by SpinRay Energy of Rhode Island can be installed by plugging the on-board microinverter into a 110 volt or 220 volt power outlet.

SunWize Partners with Clean Power Finance to Expand Portfolio of Residential Solar Financing Solutions

Solar finance products such as leases and power purchase agreements (PPAs) are crucial tools for solar professionals who want to expand their business. Clean Power Finance’s financing solutions offer solar professionals and distributors a variety of solar leases and PPAs, driving competitive prices and allowing installers to tailor options to homeowner preferences.

Guest Post: Solar Energy – Making the Switch to a Greener Future

When most people think of using solar energy in their homes, they envision massive arrays of solar panels attached to the roof and complete detachment from the traditional power grid. Unfortunately, harnessing the sun’s energy to the point of being able to go off the grid is still cost-prohibitive for the average homeowner, particularly if they own an existing property. There are ways to help offset these costs, but there are also a number of ways to utilize solar power in the home without a complete overhaul.
