Hi David,

Unfortunately, there is no single answer for your questions, since there are a lot of factors tightly related to the consumer price.

Firstly, there are matrix of energy sources to be used as conventional energy in the grid. For example, there are coal, oil, natural gas, or nuclear to be used as main source of energy. Nevertheless, none of these sources are being used as a sole energy source for any country. Each source would be used in a ratio/proportion, and the price will depend on which one is the main source, as every sources have their own price.

Secondly, the same condition also applies to the RE being injected into the grid (e.g. solar, wind, biomass, biogas, hydro). The price for generating these REs varies and so their proportion in the grid.

Thirdly, there are also government policies. Some countries do not regulate consumer price, and highly depend on the producer. Yet, other countries do regulate prices, including producer and consumer prices. In these regulating countries, the price is indeed heavily depend on the government policies, regardless the actual cost for power generation.

Hope this answers your question.

Cheers.

At present cost increases but long run will provide lowering considering environmental benefits and longer life of engines.

Energy variety is essential for all countries. However, the customer could reduce the electricity bill by installing a rooftop PV system. The grid-connected PV systems are particularly striking in displacing electrical power bought from the grid maximum demand hours, which usually coincide with maximum sunlight hours. The peak demand surcharge included in the commercial customer’s bill is electrical companies so that PV systems can significantly reduce these bills. The same thing is applying to other renewable energy sources and technologies. This situation will make mutual benefits for public utility and costumers. So, the answer is: energy price for the customer reduced (if he participates).

Depending upon the amount of renewable energy, a large increase of renewable energy can shift time-of-use peak pricing to a different time of the day, when renewable energy is less plentiful. In areas with large amounts of solar energy generation, such as California, daytime electricity prices are dropping during the day (9AM-4PM) and increasing during a newly defined evening peak period (~4PM-9PM). In some areas (i.e. Texas) where wind power is plentiful, electricity is becoming very inexpensive at night.

Dear Mr. Ortiz! This is a very interesting question to research. Any citizen of a country could be interested. So I went to the Internet and tried to find research papers from which one could draw at least some kind of prediction (documents enclosed). There are huge amout of factors at play that lead to a certain amount of scenarios: so I limit the conslusions referring only to EU. Based on the findings, one can claim that the EU will find policy solutions that enable renewable energy facilities to enable increased production of energy at a lower price-level in the long run. Still in the short run energy prices might get even higher.

I suppose that would make prices more affordable for the consumer.
