With the boom in renewable energies, many individuals have bet on them. However, a WWF study shows that there are many myths surrounding renewables that put off many investors.

Myth #1: Renewable energies are more expensive

This is possibly the most widespread myth about renewables. However, it is not only a lie, but the opposite is true. While 15 years ago their costs were very high, thanks to technological advances, they have become considerably cheaper.

In 2018, IRENA (International Renewable Energy Agency) published an article on energy production costs. In it, it highlighted that solar and wind energy were the cheapest. Over the years, as more and more is invested in them, costs have gone down. However, these have increased by up to 26% with respect to the initial investments.

Myth #2: It is impossible for all energy to come from renewable sources

Another myth is that fossil fuels will always be needed to produce energy. This fear is associated with the fact that, in the coming years, the increase in energy demand will triple. Even so, there is a wide variety of renewable sources that allow for a sustainable energy transition. The problem comes because some of them are not yet as exploited as wind or solar. This is the case of tidal energy, where there are pioneering projects but the costs are too high for it to be economically viable.

Myth #3: Photovoltaics do not produce energy at night

Part of the statement is true, however, it is not counting on the batteries that store the surplus generated. Although it is correct to say that photovoltaic energy is not produced at night due to the absence of light, this is not a problem today thanks to the storage generated. The energy surplus produced throughout the day is stored in these batteries, which will be used in the hours of less sunshine.

Myth #4: It takes many years to make the investment profitable

Both the investment to be made and its profitability will depend on the energy source and its subsidies. In general, photovoltaic energy is the most profitable and the return on investment usually occurs in the first 5 years, although in a house it may take a little longer. The location of the panels and the way in which the energy is consumed must also be taken into account.

Myth #5: They “steal” land for agricultural purposes

Another common misconception is that wind and photovoltaic farms “steal” land intended for agricultural use, which is not true. Normally, these types of farms are usually located in desert areas or, in the case of

It is a common misconception that the installation of wind farms results in the loss of land for agricultural purposes. However, this is not entirely true. Although these farms require a large area of land for their installation, the actual loss of land is minimal. In other words, farmers can continue to use these lands for their activities.
