ENERGY
Heating
For the heating to be truly effective, it must begin with a Good insulation parts and housing. Heat losses consume energy, and affect the quality all the facilities. For example you should give priority to the double-glazed windows. You should check the insulation from floor to ceiling, through the roof and walls. First, measure the thermal conductivity called lambda, which is the benchmark. (A coefficient of less than 4 or 5 is good) . On the other hand, the thermal inertia is also taken into account. Indeed, the capacity of your facility to store and release the heat is another criterion fundamental. On heating, both options are of course conventional electricity and gas, but new environmental requirements have promoted the development of several alternatives.
The Gas
Several types of gas exist, town gas or natural gas is still currently one of the most used for heating. It is doomed to disappear in less than 50 years if world oil consumption does not reduce. Natural gas, however, requires a distribution network of buried nearby. It also grows more every year. We also find the propane or LPG, which provides a good efficiency with condensing boilers. But the share of gas market declines in new construction because only 29% of new homes are heated with central heating gas, against 43% in 2004. Gas heating also has the advantage not to dry the air and can heat a room evenly, thanks to the thermostats.
The Electricity
Regarding CO2 emissions, electric heat is naturally much better than burning oil, gas or coal. The heating-electric the advantage of eliminating the constraints of fuel supply, maintenance of lamps. It is more hygienic, since it removes the fumes. However, it is substantially more expensive, when electricity is produced thermally. This disadvantage disappears with electrical energy from nuclear power can be cheaper. That energy is the easiest to implement because the wide ranges of heaters require no connection. Unlike other methods of heating, the price of heating electric consumption is stagnating. Finally, the design of electric heaters is so varied that it is easy to find one that fits inside.
The Oil
The heating oil is undergoing major improvements through modernization of equipment and facilities. Heating oil to largely proved its value during his last years with very competitive prices compared with average prices of other energy sources. However, it is declining because no new facilities are made with oil, as it is now surpassed by other energy sources more economical and less polluting. It works perfectly to heat large areas in cold regions. Cons by a boiler fuel is more expensive than an equal power boiler to gas. His prices directly suffer from soaring oil prices. Storage remains a major problem because you have to install a home tank and large capacity to regularly fill a tanker. Furthermore, oil is not renewable energy, like oil or natural gas, and despite recent advances, oil remains a source of dirty energy.
Wood Wood used as energy source in habitat represents 4% of primary energy consumed in France is the main domestic source of renewable heat. Wood is a cheaper fuel. The timber industry is organized more for the wood energy prices remain stable over time. France has an abundance of this raw material with a forest that covers nearly 28% of the country, representing 15 million hectares with a growth rate of 10% annually. The wood is renewable and does not exacerbate the greenhouse effect because its combustion produces only as much CO2 as the forest itself. The Fuel is readily available through home delivery. The performance of some units are equivalent to boilers oil or gas. You get a tax credit of 50% established by the state to encourage the purchase of these ecological units, offsetting the extra cost, if any. After deducting this tax credit, the price of a wood boiler becomes identical to that of a gas boiler.
The Solar
If technical changes occur in the next few years, solar energy could provide 100% needs. One advantage of solar heating systems is to use sunlight as energy to heat hot water and heating without the extra energy costs. The use of solar energy does or polluting emissions or hazardous waste. Using solar energy also helps conserve fossil fuels or fissile and reserve their use for specific uses more than just heat. Contrary to popular belief, a solar thermal system, namely a water heater or a solar heating can be installed anywhere, including in the less exposed as Northern France. Solar radiation energy is clean, it is the only non-polluting energy. On the other hand, it does not alter the thermal balance of the Earth, so there is no ecological imbalance
We now turn to another expenditure of energy is electricity. Reflexes are needed to consume less. "If Europeans extinguished all their electrical appliances instead of leaving them on standby, they would save enough electricity in the order of consumption of a country such as Belgium, "said Renita Bhaskar, coordinator of a campaign launched by the European Commission to raise awareness on the environment.
Here are some tips to save electricity. Defrost regularly your appliances because 3 mm of ice in a freezer or refrigerator leads to overconsumption of electricity that can reach 30%. As the dust from behind the refrigerator can increase consumption by 2 to electricity. We must therefore regularly clean the back of it. Connect your video equipment to a power strip with a switch or a car that cut standby allows you to stop all devices in a single gesture if you do not use them, because for example a computer to sleep, like a television or other increases your intake of 10% electricity. Prefer when buying a dishwasher, washing machine, dryer or other major appliances that those bearing the symbol "Energy Star". They consume 25% less energy than other models just as recent. Close as soon as night falls on winter days your shutters and drapes. When you aerate the winter, do no more than 5 minutes to prevent your room from cooling too quickly and cut the electric heating systematically. Finally, clear space in front of the radiators Radiant heaters especially not to block the heat and clean the dust back regularly to avoid excessive energy consumption.
