The news these days, report the serious consequences that the meteorological phenomena are causing to our national energy system.

In light of these events becomes more and more important to spread with greater commitment plants for the production of energy from renewable sources.

Fortunately in our country there is a fairly comprehensive legislation regarding incentives to the diffusion of renewable energy. The main purpose of this is related to the photovoltaic better known as the "Conto Energia". We arrived in his fourth (4) version that is expected to end in 2016, subject to early achievement of the share incentive power before this date.

The electric water heater is one of the main causes of domestic consumption of electricity. I'm definitely very practical. They can be installed anywhere there is an electrical outlet, they are cheap and do not require complicated maintenance. However, have the handicap of using a large amount of energy to heat the water. In the long run your monthly electricity could offset the initial savings.

And 'advisable to install the electric water heater only in cases where it is not possible to also use alternative systems (eg, gas boilers, solar thermal panels). In case you already own an electric water heater, you can still optimize its use to obtain substantial savings in the bill.

Never before in recent days, the energy issue is holding forth all over the world. The recent events related to nuclear power plants and controversial benefits arising from them, suggest more sustainable development policies.

The watchword is: savings. Energy, and economic. To do this we need to rethink a targeted and intelligent energy management, waste-free and relapse-free environment.

One aspect of this new way of seeing is the containment of heat. Often the materials used to build windows and doors of our homes "run away" most of the warming, forcing to leave switched on radiators and boilers. So the energy is dissipated, while continuing to use it, with all the attendant environmental problems. A little 'how to inflate a punctured balloon: a waste of breath.

There are some instances of users who have been delivered of the invoices relating to electric utilities, bearing of objections quite high and abnormal. Figures that roam frequently also around five or six thousand euro.

Such invoices involving exposure to very costly for users, since in most cases they are invoices adjustment. Bills within which, the single seller recalculates the consumption of a specific user, since for some time, or even for years, it has not been able to bill taking into account the actual consumption. In the absence of reliable data, however, the seller issues the invoice, but the consumption figures indicated are "estimates," or refer to a flat-rate calculation determined based on the average consumption of each user. Invoices for settling delivered to many users reconstruct even consumption made from 2007 to 2011.

The thermal transmittance of a window is calculated using the standards of the series EN ISO 10077. The numerical method for calculating the transmittance has significant benefits compared to the simplified method, especially now that the legislation for the energy certification is very strict.

Let's see why.

This in simple terms, the thermal transmittance of a window is a physical quantity that represents the amount of heat that it must not pass. The higher the transmittance value, the more there will be heat transfer between the building and the outside. Since the heat goes from "hot" to "cold", this will disperse outward during cold days, and vice versa, will come during the hot days.

The date is approaching: the next September 1, 2012 in fact, the traditional incandescent light bulbs with power ranging from 25 to 40 watts remained outstanding, will no longer be produced. How to choose the led lights for the house? With an eye on the price of course, but also considering the quality of the light and use in their environments.

While it is easier to refer to classes of energy efficiency, luminous flux (lumens) power (watts), average life in hours and luminous efficiency (lumens / watt), on the other hand we have the color temperature (K ) that can be warm white, neutral or cold (with shades of red, blue, green and yellow) and color rendering index (Ra or IRC). It was in the latter we have to pay attention if we are to illuminate the space where we spend a lot of time, especially for read or write, in this case, in fact, the index should not be less than 85.

The oven stoves are more environmentally friendly, more efficient, healthier, safer and more beautiful than all modern heating systems. Why are not there more and how you can do to bring them back?

A wood kiln is a kiln very efficient and robust that radiates heat throughout the day. In the United States it was introduced only 20 years ago, but in Europe the technology is at least a thousand years old. Especially in Russia, Scandinavia and Central Europe in the stove oven has a long and rich tradition.

In the eighteenth century, several European governments financed research to improve the technology as a way to overcome a severe shortage of firewood: a green technology before the term existed. However, its further development and and its spread were thwarted by the arrival of coal, gas and oil. The oven stoves are large, heavy and slow, but they offer so many advantages that - again - deserve to be subsidized by the government.

The beginning of autumn is the best time to see if the heating boiler still enjoys the full efficiency. Discover the existence of a fault until the arrival of the cold weather is the worst thing that can happen.

In the early days of the cold technical maintenance companies are literally bombarded with calls and the waiting list of the interventions also extends to several days. Therefore, the first rational rule is to be proactive: to carry out the annual maintenance of the boiler at least one month before the time of ignition. Eg. in October. Another reason to perform maintenance and cleaning of the boiler is to ensure a good efficiency of operation.

A boiler is not in perfect working increases the consumption of gas and your spending on your bill. Furthermore, to obtain a correct management of the fumes is required every two years to perform the analysis of the fumes, as well as the law allows. Every 2 or 3 years, during the summer months, you also verify the state of the pipes where possible. Incorrect insulation of the system can lead to unnecessary and significant loss of heat produced by the boiler.

Autumn is the time of the first cold, it's raining, it is moist, surely it is good to turn on the heating.

But if not enough, as it is better to warm up? Better a heater or stove? Which of the two is more efficient? Which heat is better?

In fact, from the point of view of the heat produced, at the same temperature environment reached. a source that is the other. After reaching the desired temperature there is a heat better than the other. Heat is energy and energy is all the same regardless of the source that produces it.

Since January 1, 2012, the application of two-tier prices is mandatory for all domestic customers with an electronic counter. Here's how to juggle the various offerings

There is talk of two-part tariff (or multi-hour) when the price of 'electricity varies depending on the time of day and days of the week in which the energy is consumed. With the two-tier prices, the cost of electricity to the end user is in fact modulated in relation to the wholesale price of production, which varies from hour to hour. During the times when electricity demand is lower, the final price is lower, while in the middle of the day, when demand is high, the price of electricity increases.
