Renewable energy technology is growing by leaps and bounds. In the last ten or twelve years, some sectors such as solar energy, wind energy or battery storage have received a great boost.

The energy system is one of the biggest polluters today. Therefore, it is vitally important to change its generation towards clean and renewable energies that do not generate emissions. Progressive technological advances must be made in renewable energies to make them more efficient and competitive.

Technology is the key to ensuring that renewable energies succeed in displacing fossil fuels such as coal and oil. For example, the technology used in solar energy generation has developed exponentially in recent years and, as a result, a solar panel can now be up to nine times cheaper than in 2006. Wind power has also experienced advances that have reduced the cost of generation and thanks to them, there has been a substantial increase in wind power capacity.

But there are many other advances in this sector that we will see in this post:

Solar Energy

Photovoltaic technology has been developing since the mid-20th century, when Bell Laboratories produced the first solar panels, but it has been in the last twelve years that we have seen the greatest advances. The process of generating silicon panels has greatly improved, allowing greater absorption of solar radiation. This means that if in 2009 a panel generated 200 watts of power, it has now tripled its capacity to 670 watts. This power continues to increase steadily and is expected to continue to grow at this rate in the future.

Wind Energy

Similarly, wind power technology has experienced unprecedented growth over the last 40 years. This growth can be seen, above all, in advances in electric generators that allow them to adapt to changes in wind speed; aerodynamic improvements in the blades; increases in the diameter of the rotor or of the blades themselves… all of which has made it possible to reduce wind energy costs in most developed countries.

In Spain, we have gone from 12-meter towers that barely managed to generate 100kW to wind turbines between 100 and 140 meters high that are capable of generating more than 5MW.



The increasing electrification that the world is experiencing in recent years is related to the energy transition towards renewable energies and will allow us to reduce our carbon emissions by 90% by 2050. Utility-scale energy storage stations are becoming increasingly common and will provide the essential capacity to create a fast-charging network for electric vehicles.


There will also be new uses for electricity that will include hydrogen production, for example. This shift to renewables is key to achieving the decarbonization of economies that is expected by 2050.

Robotics & Automation

As the energy transition towards renewable energies takes place, we have seen how important it is to improve the technology associated with this type of installations. In recent years, digitalization sets the trend along with the implementation of robotics or big data. The energy sector could not be different. Accelerating the development of robotics will be decisive in achieving net zero emissions. The tasks associated with the installation of renewable projects are becoming increasingly complicated, requiring the application of robots and drones. For example, in the construction of off-shore wind turbines.

Progressively, robots will not only handle routine maintenance tasks, but will also improve the processes and efficiency of the generators.

Energy storage

The search for new solutions for energy storage is an urgent need that we have already discussed in previous posts. Energy storage could be the key to the definitive implementation of renewables and it seems that the next few years will be very important in this regard. The search for new solutions that allow energy from green sources to be used a posteriori has already come a long way. And it is expected that new forms of electricity storage will soon be introduced on the market.

Lithium batteries will expand their storage capacity and power exponentially. In addition, multiple technologies have been developed, such as silicon or flow batteries, which hold great promise.

We will see what happens in the coming years, but technology will play a very important role in achieving the 2050 decarbonization and climate neutrality goals. It is very important that we continue to move in this direction and that companies continue to invest in innovation, as Univergy Solar has been doing for years.
