All you need to know to produce your own electricity at home. (Final part)

Following the thread from my last article I did argued that today more than ever, it is essential the introduction of renewable energy sources so that we alleviate external dependence on energy and with the intention of facilitating access to heating and hot water at low prices, in addition enabling the rehabilitation of buildings with the aid of the administration to encourage energy saving and efficiency. 

1.   . Big brother.

 The proposed royal decree does not prevent the user to store in batteries the power to be used at any time when the consumer sees fit. In the event that the batteries are charged from the national grid network, your treatment will be like any electrical consumers, whereas if it is loaded with self-generated energy itself, you will not be charged any taxes or extra costs.

Moreover, the bylaw contains various articles dedicated to the auto consumer for the purpose that consumers may benefit from these arrangements. However Big Brother (The Government) is imposing an obligation to inscribe the installation under this Royal Decree.

 

2.    Savings for the islands.

 

Due to the high cost of generating electricity in the Canary and Balearic Islands a tax is levied on every Kw of electricity sold. Power generation in the islands is more expensive than on the mainland because conventional thermal technologies. Therefore, to reduce the cost of electricity generation in the islands, an incentive to consumption is set to reduce costs of the system. Incentive that the rest of electricity users have to pay.

 

A.   Arguments on favour to install photovoltaic cells.

1. In Spain, a country with high insolation, high price of electricity and low price of photovoltaic installations, do not need any bonus or incentive to consumption, if just all sorts of bureaucratic obstacles were removed the auto production of electricity would be even better.

 

2.   Down with prices

According to a study on the price of photovoltaic solar panels it shows that their prices have fallen between 65% and 75% between 2009 and 2015, and the price of energy has increased by 80% since 2008, In the field of wind energy the cost reduction has not been as drastic, but it has been important, the cost of turbines has been reduced by almost 30% since 2008 causing - among other actors - the cost of wind power fall by 18% since 2009.

 

1.   A positive ripple effect

With the passage of time there is growing evidence that renewable energy has a positive ripple effect throughout society, while advancing in the economic, social and environmental aspects. In fact, a recent Japanese study, according to which the benefits of renewable energy are two to three times greater than the costs, including savings in fossil fuel imports, emissions of CO2 and economic repercussions.

A paradigmatic example of this effect is provided by Spain. Oddly enough, the report notes that renewable energy in this country prevented the import of 2,200 million euros in 2010 in buying fossil fuels apart from that renewable technologies can bring electricity to many people who previously had no access to it. In this area the most striking example is Bangladesh, where 13 million people have gained access to electricity through photovoltaic.

 

The benefits of renewable energy does not end here, because among others, renewable energies do not deplete natural resources, create many jobs-now employs between direct and indirect jobs to 6.5 million people and, above all, they offer a roadmap to reduce emissions of greenhouse gases, a major cause of global warming.

The target of 100% renewable energy is no longer an unattainable myth and today many countries can boast of being on the threshold goal. A few days ago Costa Rica confirmed that in 2015 they generated 99% of its electricity from renewable sources.

 

On this side of the Atlantic, or rather, in the Atlantic, Iceland offers a similar example. The country currently generates 100% of its electricity with renewable energy: 75% produced by large hydroelectric plants, and 25% of geothermal energy. Similarly, Iceland covers 87% of its demand for hot water and heating with geothermal energy, mainly through a large district heating system.
