Renewable Energy on the Liechtenstein’s stamp.

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.
During the five-years from the end of 2004 through 2009, worldwide renewable energy capacity grew at rates of 10–60 percent annually for many technologies. For wind power and many other renewable technologies, growth accelerated in 2009 relative to the previous four years.
The “Renewable Energy” series of stamps is devoted specifically by Liechtenstein Post to these energy sources, which are characterized by being self-renewing and thus sustainably available resources.
The first part of this series highlights “Hydropower” (face value CHF 1.00), “Wood” (face value CHF 1.40) and “Near-Surface Geothermal Energy” (face value CHF 2.80) as such renewable energy sources.

“Hydro-power” (face value CHF 1.00).
Energy in water can be harnessed and used.Many forms of water energy such as Hydroelectric energy,Micro hydro systems,Run-of-the-river hydroelectricity systems and Ocean energy describes all the technologies to harness energy from the ocean and the sea.

“Near-Surface Geothermal Energy” (face value CHF 2.80).Geothermal energy is energy obtained by tapping the heat of the earth itself, both from kilometers deep into the Earth's crust in volcanically active locations of the globe or from shallow depths, as in geothermal heat pumps in most locations of the planet. It is expensive to build a power station but operating costs are low resulting in low energy costs for suitable sites. Ultimately, this energy derives from heat in the Earth's core.

“Wood” (face value CHF 1.40) The proportion of wood in the biomass is to be substantially raised in the coming years by, among other things, increasing the number of wood-chip heating systems installed in public buildings.
Some companies have been building refineries that can process biomass and turn it into ethanol and producing enzymes which could enable a cellulosic ethanol future. The shift from food crop feedstocks to waste residues and native grasses offers significant opportunities for a range of players, from farmers to biotechnology firms, and from project developers to investors.

I just stumbled across this and I'm SO glad I did. Thanks for all the useful information.
