Clean Energy through the Roof Glass

Glass roofs can be used as a self-generating source for heating households, by capturing solar heat. An swedish invention has developed tile formed glassparts that captures the sun heating and between the roof battens are built special liquid absorber models that harvests sun’s energy and coverts the energy to heat. Aesthetic it gives the roof a nice icy look. The system cuts also the energy costs significantly all year around.

What is Geothermal Energy?

Geothermal Energy is generated and stored in the earth, under the soil. It is earth heat converted to energy. This kind of energy has been used since ancient Roman times from hot springs, and as other environmental friendly energy sources it is nothing new, but just modernized. Geothermal power is cost effective, reliable, sustainable and environmentally friendly. This alternative suits well for all types of energy consuming areas as industry, greenhouses and homes.

Geothermal sources under the soil releases greenhouse gases, but the emissions are much lower that fossil fuels and is a good alternative to replace usage of fossil fuels. This energy alternative can easily cover all of the humanitys needs. It is an energy source that will grow significantly the coming years as the investment costs has reduced and people has showed interest to pay more for renewable energy.

Two sources for geothermal energy are magma and hot water springs

Thermal energy plants was before built only where high temperatures were to be found close to the surface, but thanks to developed technology as e.g. better drilling equipment, the areas are today wide spread. Thermal energy today is converted from hot waters to magma. Almost anywhere the temprature three meters under the soil is between 10-16 °C (50-60 °F) and this is enough to install a heat pump.

Why Sicilian oranges are top quality

Sicily is one of the largest orange districts in the world. Also the quality is one of the best because of the nutrient rich soil thanks to an active volcano Etna. Sicily is also a water rich area and most days during the year are sunny. But the major factor that makes sicilian oranges top quality are the cold nights and warm sunny days. The humidity on the leafs, as you can see on the photo, is not caused by rain, it is caused by the cold nights that gives the perfect conditions to produce juicy oranges.
