Greenpeace keys to understand the importance of renewables
The organization Greenpeace once again draws attention to the importance of renewables in the country of the Sun, Spain. It stands out as an energy policy that affects the benefit of obsolete and polluting energies has a direct and forceful impact on household bills, preventing the benefit of all the environmental and economic advantages of the two greatest energy opportunities that are currently being wasting in the Spanish territory: renewables and possible energy savings.
We remember that the Greenpeace institution last year I published a report calledEnergetic [R] evolution, which demonstrated that it is possible to have a 100% renewable future if there is a political will for energy change.
Now, it returns to affect the benefits highlighting six key points that show thatIf the new Government stops "torpedoing" energy savings and the renewable sector to safeguard the interest of electricity companies, we would really have benefits in all sectors of the population and, above all, a balance in that energy bill that presents significant deviations depending on the season of the year.
1. The cost of electricity variable according to the energy sources
In Spain the cost of electricity changes depending on which technologies are provided at each hour from day to day of the year. It is set by means of a wholesale market that sets the price every hour with a certain "marginalist" mechanism. That is, the entire stock of the most affordable and cheapest energy source is acquired first.
From there, they go on to acquire the most expensive ones until they cover all the electricity needs expected in the country. So the final price - to a greater extent - is going to be determined by the most expensive source.
2. Renewables are the first energy sources to enter the market
When starting the acquisition of energy by the most affordable and cheap, the first energy sources to enter the market are those of the renewable sector (which offer their production at practically zero cost, taking into account that the wind and the sun are free, with a few low maintenance and operation costs) and energy from nuclear (which actually outsources most of its environmental costs, such as the management and maintenance of nuclear waste or the problem of limited liability in the event of a major accident).
If more electricity is needed to satisfy all the country's demand, they go in search of more expensive energy, such as that which comes from lignite or from gas that have a high rate of polluting emissions and CO2.
It is important to review two articles of interest about renewables; the first are the types of bioenergy that take advantage of biomass energy and the second, tidal energy in the marine energy sector, which is on the rise throughout the world due to the production of clean energy on a constant basis.
In the end, all of them together will receive the same price for the electricity sold to the wholesale market, that of the latest technology to enter, come on… the most expensive!
3. Higher wholesale cost with less renewables
The less renewable energies enter the market, in general, the higher the wholesale cost of electricity will be since it will increase the probability that it will be necessary to use more expensive and polluting plants such as lignite and gas to cover the needs of electricity in each and every moment.
4. Summer. Increased consumption and less wind and water
Almost every year around the months of January, June and July 2 things happen: an increase in electricity demand as a result of the rebound in cold or heat (heating and air conditioning). Generally, in summer there is less wind and less water availability in the swamps, so we have less renewable energy to consume. These 2 factors make it necessary to purchase more energy from expensive and dirty sources to be able to cover all the demand.
To understand it a little better, we provide the summary graphs for this year by months. What is renewable energy production and energy demand.
5. Invoice indifferent to energy savings
Even if electricity consumption is reduced to zero, the consumer must continue to pay part of the fixed electricity bill that is proportional to the contracted power. This fixed term has grown disproportionately in recent times as a result of pressure from electricity companies, who do not want to see their profits diminish even when the crisis or energy efficiency measures have significantly lowered the demand for electricity. This causes that the decrease in consumption in the summer at home is practically not reflected in the bill.
It should also be noted that the net price of electricity for domestic use continues with rising statistics …
6. Little solar energy installed
If we look at Spain, one of the countries with the most sun, there is very little solar energy installed (4.8 GW): only a quarter of that in Italy (18 GW) and only a tenth of what they have in Germany ( 40 GW). In addition, the evolution for new facilities is directly paralyzed …

We must remember that Greenpeace organization demonstrated how renewables are the formula for a sustainable future, both for the environment and for the economy and citizens, being that it is possible to have a 100% future.
