World solar photovoltaic (PV) installations were 2.826 gigawatts peak (GWp) in 2007, and 5.95 gigawatts in 2008, a 110% increase.[25][26] The three leading countries (Germany, Japan and the US) represent nearly 89% of the total worldwide PV installed capacity. According to Navigant Consulting and Electronic Trend Publications, the estimated PV worldwide installations outlooks of 2012 are 18.8GW and 12.3GW respectively. Notably, the manufacture of solar cells and modules had expanded in coming years.

Germany was the fastest growing major PV market in the world from 2006 to 2007. By 2008, 5.337 GWp of PV was installed, or 35% of the world total.[8] The German PV industry generates over 10,000 jobs in production, distribution and installation. By the end of 2006, nearly 88% of all solar PV installations in the EU were in grid-tied applications in Germany.[2] Photovoltaic power capacity is measured as maximum power output under standardized test conditions (STC) in "Wp" (Watts peak).[27] The actual power output at a particular point in time may be less than or greater than this standardized, or "rated," value, depending on geographical location, time of day, weather conditions, and other factors.[28] Solar photovoltaic array capacity factors are typically under 25%, which is lower than many other industrial sources of electricity.[29] Therefore the 2008 installed base peak output would have provided an average output of 3.04 GW (assuming 20% × 15,200 MWp). This represented 0.15 percent of global demand at the time.

Q: When should I use my Emergency Heat?
The Emergency Heat switch on a Heat Pump thermostat confuses many people. The fact of the matter is that most people don't seem to understand exactly what Emergency Heat is and when they need to use it. Many people think that Heat Pumps don't work in cold weather and they are supposed to use the emergency heat whenever it gets really cold... Wrong!



Q: What is Emergency Heat?
Simply put, all Heat Pumps in northern climates [below 35 degrees] need a supplemental heating source. Usually it is in the form of electric resistance heating. This is an all-electric Heat Pump. It can be a gas, oil, or hot-water back-up system as well. The supplemental heat is also referred to as "second-stage" or "back-up" heating, "first-stage" being the Heat Pump only. The supplemental heat is also what is used as the Emergency Heat.

Different systems have different ways of determining when the second-stage comes on to assist the heat pump but it is always done automatically. So the two stages will work together in the colder months and it is not necessary to switch your thermostat to Emergency Heat. Now we know what supplemental heat is and that it is also used for Emergency Heat.

The federal government offers new geothermal system tax credits for residences.
Originally, the Residential Renewable Energy Tax Credit enacted in 2005, only offered tax credits for solar electric systems, solar water heating, and fuel cells. The Energy Improvement and Extension Act of 2008 expanded the tax credit to include geothermal heat pumps.
Though the act was passed recently, tax credits are retroactive to Jan. 1, 2008, and expire Jan, 31, 2016. Homeowners may claim a 30% credit on qualified expenditures for a system that services a dwelling located in the U.S. and used as a residence by the taxpayer. The maximum incentive is $2,000. The home served by the system does not have to be the taxpayers’ principal residence. Expenditures include labor costs for on-site preparation, assembly or original system installation, and for piping or wiring to connect a system to the home.
The geothermal heat pump unit must meet the requirements of the Energy Star program in effect at the time the installation is completed. The act also eliminates the solar-electric credit cap effective Jan. 1, 2009.
