Today’s energy market offers dozens of suppliers to choose from, but in reality 2-3 big players dominate the market. Even so, it can be said that there are ways to get rid of at least part of this dependence.
Let’s not look for any magic and sorcery in this, it’s very simple. A lot of you have heard about it, others are thinking about it, some have implemented it, and others don’t care. It’s basically these 3 main sources.
The most well-known are photovoltaic panels, which produce electricity by converting sunlight. The power plant can be placed virtually anywhere it shines. Then there are small hydroelectric plants, which have their advantages over solar ones, but also their disadvantages. The advantage may be that the water is always flowing, but the disadvantage is that lately there is less and less of it. Finally, wind – the disadvantages here are definitely the higher acquisition costs, and the higher dependence on airflow – hence the location of the wind turbine.
Usability during the year
Although the sun can be said to shine all year round, during autumn, winter, and early spring its path in the sky is too low and its duration too short to provide enough illumination to generate enough electricity for our total consumption. In contrast, hydroelectric power can produce power all year round, but only if there is sufficient water flow. As for wind, the situation there depends entirely on its occurrence, strength and frequency.
What to choose
Each solution has several aspects to choose from. First and foremost is the availability of the resource. Sun practically anywhere, with water it’s worse, and the same with wind. Another aspect might be the type of property where the resources will be used, the number of people using the property, what will be the biggest energy consumer – water heating or heating or something else, and we could certainly find other aspects such as acquisition costs, space requirements, or the lifetime of the whole system. We’ll cover how to do that in a future article on this topic.
