What exactly is an energy efficient home? Provided it meets with it’s owner’s energy demands, an energy efficient home is one that reduces energy waste by reducing unnecessary consumption of energy; consequently, energy efficient homes reduce their environmental impact by reducing emissions of greenhouse gasses. Comparing an energy efficient home with a conventional home, one… » read more
By solar panel efficiency we refer to the rate at which a photovoltaic panel converts solar energy into electrical energy. In general, a typical efficiency level of PV panels ranges between 12-16%, though recent technological improvements suggest we will soon be talking of efficiencies in the range well above 20%! Solar panel efficiency Solar panel… » read more
What is a “green-roof?” Some say the term conjures up images of green vegetation on a building’s roof; others refer to the concept of making a building’s roof green from an environmental standpoint with green energy solar panels. It turns out that green vegetation on your roof can actually help boost your roof-mounted photovoltaic panels.… » read more
Whether you are interested in installing solar panels for your home or looking into a commercial solar photovoltaic power plant, before commencing on such an investment you need to identify what your project entails and assess its financial viability. Herein we provide some essential advice on making such an assessment of solar panels for your… » read more
Photovoltaic Solar panels cost has been diminishing drastically in the past years and is expected to continue its down slope for some time; the cost of solar panels is a variable that actually depends on the time, place and scale of your solar panel installation.
The definition of zero-energy-home or zero energy building is often misunderstood as a building having zero energy consumption. A zero energy building simply refers to a building producing the same (or more) amount of energy than what it consumes within a single year.
US Solar photovoltaic (PV) market is healthy and booming, with Solar energy installations expected to grow further in 2012. According to the US Solar Market Insight report for 2011 and the GMT Research, US solar Photovoltaic (PV) installations have more than doubled,
Energy Storage is key for Renewable Energy Sources’ penetration into power generation. Renewable Energy Sources (RES) have become of particular importance in the establishment of green, environmentally friendly applications; thus they constitute a crucial piece of the puzzle for achieving global environmental, economical and social/political sustainability.
When we talk about renewable energy sources (RES), we define them as replenishable energy sources freely available by nature, such as solar energy – solar energy facts, wind energy, biomass/biofuel energy, water energy and geothermal energy. To exploit renewable energy sources
When we talk about green buildings we refer to the application of techniques and principles for reducing the environmental footprint of ‘having’ and using a building – see intuitive environmental awareness. Constructing and maintaining a green building incorporates applying green principles at all stages; designing, building and using it. In general green building practices may… » read more
