Critiques at new Energy Bill

New controversy over Third Energy Bill approved in July and published in the Official Gazette. The decree, as we wrote, regulates the incentives and aids in the production of electricity from photovoltaic sources for the period 2011 to 2013 and said at the same time, the Guidelines for the authorization of renewable energy plants .

The new energy account only applies to plants that entered into service after December 31, 2010 and to increase to six classes of power, but also provides a simplification to only two types: those made on buildings and those located on the so-called " other plants. "

The risk of electrocution on photovoltaic systems

The incentives for photovoltaics in Italy and a method for choosing the lightning protection systems in order to protect photovoltaic systems by direct or nearby lightning strikes.

In recent years, governments of many countries in the world have tried to increase the share of electricity generated using photovoltaic systems through to various types of incentives.

In Italy, the construction of photovoltaic plants is promoted as defined by DM February 19, 2007 [1], through the adoption of the so-called "energy account", the Electricity Services Operator (ESO), pay to the owner of a fee (incentive fee) for all the energy that is produced from 'plant over twenty years. This incentive applies to today, around 0.40 € / kWh and can vary by ± 20%, depending on the plant size and its level of integration into the host structure. Preference is given to small installations and more integrated. The premium may be increased by 5% if special conditions exist (eg, replacement of asbestos roofs), or up to 30% if the PV is combined with the efficient management of electrical energy.

Energy: kWh saved cost less than renewable energy

The European Union has joined the Kyoto Protocol, which set the goal of the so-called 20-20-20, which commits member countries to a coherent policy.

There are two ways to go: energy efficiency and renewable energy sources.

Given that the cost of 1 kWh saved is much lower

the same kWh produced by renewable sources and to save 1 kWh / year in energy efficiency are needed 1.8 euro investment, whereas to produce 1kWh/anno with photovoltaic panels are needed 5.0 euro of investment, it is clear that saving energy passes mainly for energy efficiency.

Green energy tariffs to save money

To date, an average family can save over € 100 a year, and at the same time, in some cases, even help the environment. Just choose the right rate.

Recall that the liberalization of the electricity market, which took place in 2007, finally allowed to suppliers selling directly to the end customer.

The consequences of the process of market opening, until now managed by former monopolist in a difficult mix of public and private interests, resulted in a reduction in the prices of electricity and gas and the diversity of supply.

Future of solar energy: less costs and more work

The plants that use the sun soddisfarranno 5% of the world's energy needs by 2020 and 9% by 2030. And 'what emerges from the report Solar Generation 2010 released by Greenpeace International and EPIA - European Photovoltaic Industry Association.

The estimates closely linked to the energy market, the report also forecasts that flanked the Equipment: Regarding the cost of photovoltaic modules is expected by 2015, a drop of 40% - a decline similar to that in the last three years - which will allow the energy thus produced to be on the market at a competitive price and comparable to that obtained from other sources, as part of an offering that will expand more and more, both in industrialized countries and emerging markets, going to cover the needs of a population of over 2.5 billion people within the next twenty years.

Buildings: feasibility, safety and energy efficiency

The National Council of Notaries and 12 consumer associations, Adiconsum, ADOC, Altroconsumo, Assoutenti, House of the Consumer, Active Citizenship, Confconsumatori, Consumers Association, Consumers League, Consumer Movement, Movement of National Defence, National Consumers Union, presented the "Guide for the Citizen "dedicated to the new building standards, in terms of safety and energy conservation, which allow the buyer to know the quality of a property to buy and the expense to be incurred for its management.

The Help "Purchase Certificate. Practicability, safety and energy efficiency in buildings", he stresses that the purchase of buildings "certified" in terms of health and hygiene, safety and energy savings, it is increasingly important from the economic point of view and environmental.

Buying Guide: low consumption bulbs

Energy-saving lamps: Starting last September 2009, began the gradual banning the old incandescent bulbs in favor of new energy-saving lamps. The replacement of old light bulbs materializes in stages, we started from the 100-watt bulbs and lamps of any type of power buffed. In September 2010, will be the turn of incandescent lamps of 75 W, in September 2011 of the 60W, in September 2012 will touch the lamps 15, 25 and 40 watts, and concluded in 2016 with the banning of all light bulbs class C.

To better convey the idea of the benefits of new energy-saving lamps must be said that the latter turn out to be mercury-free and provide an average reduction of 80% of cost of lighting: with the same lighting, in fact, saving light bulbs energy consume one-fifth of a normal incandescent bulb. For example, you can replace a 100W incandescent bulb with a 20W energy saving and the average length ranging from 5,000 to 15,000 hours.

Eco-content building new EU directive

Already been finally approved by the European Parliament on 18 May, the European Directive 2010/31/EC on the energy performance of buildings was published in the Official Journal of the European Union last week. It will enter into force in three weeks and will replace Directive 2002/91/EC, which will be repealed from 1 February 2012. The new Directive promotes the improvement of the energy performance of buildings, taking into account outdoor climatic and local conditions as well as the provisions relating to indoor climate and effectiveness in terms of costs. The measure is defined as the common general framework for a methodology for calculating the energy performance of buildings and building units that Member States are required to apply in accordance with Annex I of the Directive.

Construction: energy certification and qualification certificates

Speaking of energy efficiency and savings one can not consider the great role played in buildings, especially considering how our cities are polluted and how many problems in terms of costs and health it creates pollution. In our system there is national legislation, as well as many regional laws laying down the criteria and how to improve the energy efficiency of buildings. The objective of the legislation is to facilitate the integration of renewable energy sources in buildings, both to ease the burden that energy from fossil fuels to meet the Community's objectives in terms of energy production from renewable sources and reducing emissions. In recent days we have also seen how this legislation could be improved and how our country is back in this field, especially compared with European directives.

Finding your way with energy saving light bulbs

On store shelves there is already a wide range of lights with low consumption, but risks confusing the customer. So, how to find the bulb that best suits your needs?

80% of all the electricity we consume in the house used to illuminate. Reduce this consumption is possible, using energy saving light bulbs and better distribution of lights in the house. The European Union has already banned incandescent light bulbs of 100 watts and by 2012 will send retired all the others, including halogen. The reason is the high energy consumption than the actual yield.
