Renewable Energy And Batteries Will Be Completely Different

By 2035, the world will do better in terms of greenhouse gas emissions. Rather, we have actually stopped emissions completely. After all, many countries have said that by 2050 they will achieve carbon neutrality and will not produce more carbon dioxide or other greenhouse gases.

This means that by that time, we will stop using disposable resources such as oil, natural gas and coal as energy. As a result, solar panels and wind turbines will be found throughout the planet. This choice is foreseeable. Economically, the cost of such renewable energy is much lower than that of “old” energy production, and it is of great help to environmental improvement.

Take solar panels as an example. By 2035, their appearance will be very different from today's, and the shape and size will be varied. There will be tandem solar cells stacked together by different solar cells. And what do you mean by each part of the stack that favors a particular spectral segment? For example, the uppermost battery can effectively absorb blue and green light and convert it into electrical energy while allowing the rest of the light to work with the red light through the underlying battery. Each part of the solar panel has its own mission, creating an efficient solar cell with an efficiency of 35%. By contrast, our current solar panels on the roof are only 22% efficient.

In addition, there are some solar cells that like to "sunbath" on both sides. These double-sided solar panels are ideal for large solar installations because they not only convert light from direct sunlight, but also absorb reflected light from the ground, which produces 25% more energy than a single-sided battery. Thin-film solar cells will also become a trend, and such batteries do not need to be used in special locations and can be invisibly implanted into windows and walls of buildings.

By 2035, the grid will also undergo a transformation. It will become smarter, consisting of smaller micro and nano networks. For example, a group of office buildings or homes will have their own nano-network that can operate autonomously and provide its own power without overloading. These nano-networks will then create larger micro-networks with the surrounding buildings.

Whether it is a solar panel or a wind turbine, or a power grid, it can be combined with energy storage. Especially when energy cannot be generated by itself, the energy storage effect of the battery becomes more important. Where does electricity come from at night, during the rainy day, when there is no wind? Therefore, by 2035, more people will realize the advantage of using batteries to store electricity. Almost every household, every district, every office building, etc. will install energy storage batteries. Lithium-ion batteries, which are now more popular, will also become more efficient and affordable.

At that time, because of the deepening of national policies and environmental protection concepts, electric vehicles will also be very popular, and cars that are not needed at night are not a large power source? And its battery can be charged quickly. Assuming that your electric car already has electricity in the event of solar power failure or power outages, you can use the car battery to meet your needs.

This is the great convenience that renewable energy and batteries bring to humans after 10 years!
