Quality Of The Environment

The global warming phenomenon has attracted increasing attention among large numbers of the general public in recent years. The Earth’s average temperature has risen by 0.750C over the course of the past century.
The crux of the problem lies in the burning of fossil fuel materials, such as crude oil and coal, which emit greenhouse gases into the atmosphere, trapping heat close to the Earth.This increased temperature causes weather changes and extreme weather throughout the world.

On June 30, 2009, Israel Post has issued the stamp series depicts symbolic images regarding to remind the Global warming phenomenon that focused to thee points : Geothermal Energy, Global Warming, and Solar Energy. All issued stamps have uniform nominal values.

This phenomenon manifests in Israel in the form of decreasing annual rainfall, harm to water sources and the growth of desert areas in the country’s southern region.
To develop alternative energy sources  which will reduce the need to use fossil fuel, thus decreasing the greenhouse gases emitted into the atmosphere.These efforts can halt the global warming phenomenon, or at least slow its progress. Renewable and clean energy sources such as wind power, geothermal power and solar power are being especially emphasized. 
Geothermal Energy
The Earth is portrayed as a boiling kettle, illustrating the energy stored within the depths of the Earth. The tab features a photograph of a geyser with an adjacent turbine for the utilization of lost heat

Global Warming
The Earth is depicted as melting in a frying pan against a red background, in contrast to the tab featuring the international graphic symbols for alternative energy, ecology and the environment portrayed against a clean environment background. 

Solar Energy
A “green” house surrounded by green vegetation appears on the Earth; a photoelectric solar device is installed on the roof of the house. The tab features a photoelectric electricity production unit and a close-up photograph of solar cells.

The greatest potential for producing energy from natural sources lies in the utilization of the sun’s rays. Israel is among the world’s pioneers in this field. The solar heated water tank was developed in Israel in the 1950’s and such tanks are currently used in most Israeli homes. Israeli companies have developed solar-thermal power stations that operate to effectively produce electricity at various locations around the world. (Resources from Israel Post News)
