CC
The consumption of energy in the countries increases every year by approximately 10 percent.
Electric companies at regional and national level are not capable of supplying enough energy for their clients and there is also a shortage of electric energy in rural areas due to lack of facilities.
Installations independent of the public network are cheaper than the same installation with cables, meters, payroll, etc.
Importance of solar systems
The current situation in Ecuador, of constant blackouts for long periods of time, and in many remote provinces, daily blackouts, will not change due to the fact that the large hydroelectric plants existing in the country, such as Coca Codo Sinclair, Paute, Agoyán, etc. they are working at the limit of their technical and resource level; that is, the amount of the water flow.
Thermal power plants (generators) cut off the largest export product: oil.
The wind will perhaps take advantage near Aloag in the mountains.
The situation in Ecuador
In the short term there will be no change in this situation, because the financing and construction of new hydroelectric plants, as in the case of the 1500 MW Coca Codo Sinclair Hydroelectric Power Plant, require years of work and studies.
The acquisition of thermal energy produced by private or state companies is not enough to solve this situation of increasing demand.
The privatization of electricity companies does not have much influence either, although this issue is a bit distorted in the national public discussion: it is obvious that in all business aspects a private company must and can function better than a state company, having control, pricing, etc. in the hands of the legislature.
All the forms of energy used that consume or convert a certain initial product, which does not self-renew, are called non-renewable: in the case of oil, we use oil until the resource ends (within a few years).
Renewable energies such as solar energy, wind energy, hydraulic energy do not run out and also do not pollute the environment, and therefore are healthier.
However, the initial investment cost for the use of renewable energy is high, but calculating the operating time, cost of distribution and maintenance, plus the cost of the resource (e.g. fuel) we arrive at the same cost in the long term.
In many cases, by dimensioning the facilities well and taking advantage of public financing, you can have renewable energy cheaper than the conventional one.
For example, the investment for a house, buying a motor generator is cheaper than the acquisition of a solar system, but the photovoltaic solar panels will work 20 to 30 years without major maintenance, the motor generator maybe 2 to 3 years (with high cost maintenance and then you have to invest again in a new motor-generator); energy from the sun is free, fuel costs.
In other countries, the situation of electricity generation and administration is better, but sometimes it depends on atomic and thermal plants, nor is it sustainable.
Solar energy is gaining increasing importance internationally. There are enough resources to obtain hydro and solar plants. There is mainly enough sun to harness this form of lucrative energy. Because any solar thermal or photovoltaic installation can last a long time and without major maintenance, it is used worldwide.
The situation in the world
90% of household energy consumption is used for cooking, mainly using gas, kerex, and firewood.
Only the remaining 10% of household energy is used for electricity, radio, television and water pumping. This amount of energy can also be generated with photovoltaic energy.
Only 10% of household energy is used for light and equipment
Renewable energy is cheaper
For the development of our country we need electrical energy.
To guarantee this public service, politicians must be encouraged to change laws and regulations to guarantee:
- A 20% increase in rural facilities (10% average annual growth plus 10% of rural facilities far from the public network)
- Applications of the regulation of private generation (or of new companies) with determined tariffs of decentralized feeding to the public network. ("T" connections)
- Clear state policies of tax and credit release for the aforementioned investments.
- In order to guarantee in rural areas and especially in areas far from the network, that there are no blackouts and that new regional and local companies can be encouraged to guarantee this service.
There are enough water resources near the mountains, and in the rest of the country it has been shown that solar energy is economical and efficient.
The resources used to generate light in the house in rural areas are kerex (Petromax), cells and batteries. Especially solar home systems have a number of advantages over other sources:
- No production of toxic gases
- No fire hazard
- Better quality light available
- Continuity of power supply is guaranteed
- Does not dump or pollute the environment with old dry batteries (which are poisonous)
- In case of using car batteries recharging them in the town, the solar system is cheaper and its handling becomes easier.
- In relation to the motor-generator there is no noise, it does not cost fuel, nor maintenance, an entire large plant for a television and a bulb does not light.
In Europe many houses are already equipped with solar "T" connection systems, feeding the public grid during the day, charging half the price of energy. At night they receive "normal" public energy by paying.
The owner wins twice: He produces his own energy and charges for it. It also has a completely maintenance-free system, because it has no batteries. These systems quietly have a useful life of more than 20 years.
The state and the electricity companies also win, they do not have to invest in new generation plants, in the increase in distribution lines, in losses in energy distribution.
Finally everyone wins: not spending non-renewable energy.
Solar electric systemsindependent and GRID injection (electrical network). Backup and protection of medical and computer equipment, radio communication, electric fences, cogeneration together with electro-thermal generators, air conditioning, etc.
Photovoltaic water pump systems that do not require batteries so the return on investment is very fast. These systems work fully automatic.
