While fuels from the forest and energy forest can be considered environmentally friendly, the recovered wood fuels surely cannot. Calorific value The calorific value is the amount of heat generated by a given fuel mass when it is completely burned and it is measured with a socalled bomb calorimeter. The higher or gross calorific value and lower or net calorific value (qgr and qnet ,respectively) can be found via the calorific

Homes are also more hygienic. Dung cakes are no longer stored in the homes. Cooking with gas takes less time than with wood or charcoal or any other commonly used fuel. It is easier to cook with gas stove. Economical Estimating an average per capita consumption of 3 kg of wood per day for energy (cooking, heating and boiling water) in rural areas, the daily per capita demand of energy equals about 13 kWh which could be covered by about 2 m3 of biogas. A biogas plant therefore directly saves forest. Annually, each biogas plant can save more than four ton's of firewood and 32 liters of kerosene. A single biogas system with a volume of 100 cubic feet (2,8 m3) can save as much as 0.3 acres (0,12 ha) of forest (woodland) each year. A recent study by Winrock, Nepal and others found that each biogas plant can mitigate about five tons of carbon dioxide equivalents per year. Dangers of biogas Anaerobic digestion systems and associated manure storage and handling present many safety hazards
Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Solar energy is inexhaustible. Noise free. Does not harm the environment. Click to edit Master text styles Second l
BARRIERS TO DISTRICT HEATING DEVELOPMENT IN SOME EUROPEAN COUNTRIES Abstract District heating (DH) offers low primary energy demand, high security of supply and small CO 2 emissions. Barriers to DH in the UK, Ireland, France, Romania and the Czech Republic have been compiled through publications and interviews. DH systems require large investments, have negative initial cash flow and long payback time, which obstructs financing. One actor should control DH from source to consumption. If the value chain is fragmented, contracts are required between the links. It increases risks and financing costs, like in the UK and Ireland, where DH is not established. There are few multi- family houses with central heating and it is expensive to build DH networks in built areas. Most French DH systems are operated according to long-term concessions by companies that sell electricity and gas. No strong actor provides unbiased DH support. In the Czech Republic, gas
