Energy takeoff 2022: US pledges 46.1 GW of new generation capacity

The use of alternative energy has become a salvation for the world. An environmentally friendly resource, available in an unlimited amount, is the optimal solution for power supply of both small appliances and large objects. Every year the number of clean energy generating capacities is increasing and 2022 should be no exception.

According to analysts’ forecasts, in 2022 the United States plans to commission 46.1 GW of new generators. Almost 50% of them are solar-powered (21.5 GW of total solar power).

In addition to solar energy, attention was paid to other options for alternative power sources. Thus, the share of wind turbines in the planned volume of new capacities will be 17% (7.6 GW), and systems operating on natural gas – 21% (9.6 GW).

Future plans

According to experts’ calculations, the total increase in US energy storage capacity will be 84%. Such results will be achieved, among other things, thanks to the construction of two new power units in the state of Georgia. These power units are capable of providing a 5% increase in the country’s electric capacity in 2022.

The US Department of Energy announces a full transition to clean energy by 2035. Given the pace of development of the “green” energy industry, it is quite possible to achieve such results. The Department of Energy has allocated $130 million for new solar energy development projects in the United States in 2020. These funds will be used to finance 67 projects aimed at introducing artificial intelligence into energy production and reducing the cost of energy from solar power plants.

Wall Street Predictions: Investments that pay off

Among investors from all over the world, the purchase of shares in companies specializing in the production and operation of renewable energy sources is becoming an increasingly popular solution. Both the solar and geothermal energy sectors are developing at a rapid pace, which has a positive effect on the overall growth of investment in these industries.

What to buy?

The rapid development of the industry is an excellent period for investment and profit. Analysts recommend paying attention to several major companies whose shares may go gold in the coming years:

  • ChargePoint (CHPT) is one of the largest networks of electric car charging stations located around the world;
  • Clearway Energy (CWEN) is a conventional power generation company specializing in the creation of renewable energy sources;
  • Darling Ingredients (DAR) is one of the world leaders in the production of environmentally friendly products for the pharmaceutical, food, feed and fuel industries;
  • Ormat Technologies (ORA) is the owner of the largest geothermal assets in Nevada.
  • It is worth paying attention to such companies as First Solar (FSLR), SPDR S&P Kensho Clean Power ETF (CNRG), Sunrun (RUN).

Acquiring assets on the US stock exchange requires a serious understanding of market trends. But given the global transition to clean energy and the plans of one of the world’s largest economies for the coming years, investing in renewable energy stocks will definitely be profitable.

Non-standard solutions: rain as a source of energy

In search of free and endless clean energy, humanity has thoroughly explored the possibilities of many resources. The energy of the sun, wind, water, earth is actively used in many countries of the world, which indicates the success of developments and implemented projects. But the search for new sources of energy doesn’t stop. In 2020 a group of scientists from the US and China developed a unique project that involves generating energy using raindrops. Yes, yes, energy from the rain! Such a solution can be a real find for regions where the sun is a rare guest.

It was also discussed earlier about obtaining energy through the use of rain. But all the methods proposed by scientists and adventurers and the prototypes of the installations presented did not make it possible to recoup the costs and make the installation profitable.

The head of the scientific group from China, Wang Quankai, presented an improved project to the world. According to the scientist, one drop of rain falling from a height of 15 cm is capable of generating an electrical voltage of more than 140 volts. The power of an installation operating on such an energy source is capable of feeding more than a hundred small LEDs. The creation of such an energy converter can solve the problem of power supply for small devices, for example, sensors in various devices. Such converters will be an excellent alternative to the already familiar solar panels, which are almost useless in cloudy weather.

It was possible to achieve a significant increase in the efficiency of rain generators by making changes to the design of the devices. Scientists have proposed covering them with polytetrafluoroethylene (PVDF) – a thin membrane of material that can accumulate a charge when raindrops hit it. The accumulation of the surface charge continues until it reaches its maximum. In this case, the drops act as resistors, and the membrane acts as a capacitor.

Work on the practical creation of the first rain generators is already underway. Its result can be special umbrellas with built-in chargers for gadgets, rain batteries for use in regions prone to heavy seasonal rainfall.

The effectiveness of such installations is also evidenced by the work of the French team of scientists led by Thomas Jaeger. Together with colleagues, he managed to assemble a similar transducer using PVDF membrane 25 micrometers thick. When drops hit the surface of the membrane, small oscillations occur on it and generate a current.

More is better

Scientists have deduced the dependence of the efficiency (efficiency) of the device on the size and force of the fall of raindrops. Thus, large drops falling from a greater height and at a lower speed are capable of transferring an energy equivalent to 12 milliwatts to the plate. Thus, a plate with an area of ​​only 3 cm2 is capable of generating a current of up to 15 milliwatts. At a high speed of falling drops, a large amount of energy is spent even in flight and during the fall, because splashing occurs.

French scientists managed to calculate the energy efficiency of rains passing over France. According to them, each square meter of land that falls under the rain is capable of generating up to 1 watt of electricity per year.

Rain energy will become a popular alternative to solar converters in the near future will be known very soon. In the meantime, scientists continue to develop the most effective installations that can prove to the world that energy surrounds us from all sides. Including – in rainy weather.
