In recent years, power companies have been a bit paranoid about solar power generation. They have been advocating solar energy and wind power for many years, and they have been encouraged to adopt it as soon as possible. As a result, they have only increased public awareness but have not generated much profit. Shareholders watched as stock prices began to fall and there was no longer a high level of enthusiasm for renewable energy. However, if they advocate solar energy first, and then degrade solar energy, then their mercenary and carbon black soul will be exposed. Consumers may also turn to greener energy suppliers.
Solar energy is becoming more and more popular. Various governments have successively introduced policies to subsidize solar panels to promote their development. In fact, whether solar energy is manufactured or installed at present is not cheap -- so those subsidies and processes are mostly implemented in legal form. In the future, households equipped with solar energy can even earn "energy credits" or real money in different ways through the "electricity feedback" process.
According to the “Electricity Repayment†scheme, for those who have installed solar power plants (or other renewable energy power plants, such as wind farms that are not part of the power company), if they have a surplus of electricity generated by using these devices, the power companies must Provide these power generators for free. And if all of the electricity you use is obtained from solar installations, the utility company will also pay or pay for the energy credits for the extra power you give back to the grid. You are no longer their customers but are charging them. According to this model, your solar array can not only make a return, but also make money for you, or at least earn energy credits (that is, free energy) so that it can be used when there is no sun in rainy days.
Now, think about millions of households that may install solar power systems, and you can understand the plight of power companies. Power companies don't like that business model, so they always delay installation.
　 Solar + Electric Vehicles: The killer application of Musk
Where did Alan Musk, the founder of Tesla Motors, break through? First, solar panels were installed on the roof, and people with electric vehicles were able to charge electric vehicles at very low cost and even for free; Second, Musk has a little-known investment: Solar City, whose website claims to be "the nation's leading solar company serving thousands of users in 14 states."
Musk is a famous solar energy advocate, not only because of his interest in Solar City, but also because he knows the great potential of solar energy revolution. He is building hundreds of Tesla supercharge stations to allow Tesla owners to drive around the United States for free, and these charging stations are often equipped with huge solar arrays, or use solar energy.
Therefore, Musk not only sold 4,000 Model S automakers for 60,000 US dollars or more in a month, but he also became a thorn in the power companies because he provided these cars with cheap or free charging. Combining solar panels with electric vehicles, it is possible to achieve killer applications in the electric sector: using solar power to generate electricity, and using electric vehicles to travel—no need to pay for electricity or fuel. There was a big deal in Musk.
　 Lifestyle revolution
There is another, perhaps more revolutionary, combination of solar energy and electric vehicles: energy storage. In the current grid system, electricity is produced on demand. The power company constantly adjusts its production capacity to meet the demand day and night, and often adjusts prices to get the maximum profit from this demand. Many electric vehicles on the market can be set to charge only when the electricity cost is low (usually at night), but they cannot effectively store a large amount of energy for use in the event of a natural disaster or a surge in demand. With electric cars today, this is also expected to happen.
Electric cars can be considered as a big battery with wheels, with huge storage capacity. The Tesla Model S weighs 2177 kilograms, and most of them are batteries, with a battery capacity of up to 85 kwh. How much energy does a household generally consume? According to the US Energy Information Administration, the average daily average is about 33 kilowatts in Oregon, and the figures in other states are similar.
This means that if the grid fails, a fully charged 85 kWh Tesla Model S can provide a home with almost three days of daily electricity. Turn off the TV, air conditioning and a lot of other appliances. This time can be extended a long time. After a major earthquake or similar disaster destroyed the main grid, households equipped with solar cells and electric cars were able to keep the refrigerator working to extend the food supply, charging the mobile phone, and keeping the lights at least until the situation was stable.
One day, various electric cars will be running on the road all over the world, each equipped with a large capacity battery. Through the clustering effect, it is not difficult to imagine that in the event of a crisis, electric fleets can supply power to the home or even the entire city's power grid. During the day, if the main power plant collapses, private solar and wind energy can temporarily take over to power the grid and charge the car. At night, electric cars keep everything running until the sun rises. This is a small-scale and large-scale symbiotic power relationship.
If this "home solar + electric car" combination is extended to millions, billions of homes, or even the world, then for many cities and countries, it is not just to deal with some sudden crisis, but to solve it. Travel problems also solve people's energy needs. Thanks to solar energy and other renewable energy sources, we no longer rely on fossil fuels, and we will usher in a new century of energy self-sufficiency. Such an energy system that does not use fossil fuels, individuals can run but can be networked, will fundamentally change the way of life around the world. Of course, this is based on the popularity of solar power generation devices and electric vehicles.
　　 Solar Power VS Power Company: Each Anqi Bit
Now, the visionary countries have realized the shortcomings of the oil economy: huge costs in exploration, refining, and distribution, serious pollution, regional price volatility, and the fact that one day it will run out. Even if people create synthetic fuels that meet current needs, they cannot really solve this problem. As long as they are burning, the harm to the atmosphere will not stop. However, free, reliable, clean solar energy will land on the roofs of the world every day.
Critics say that if everyone buys an electric car and plugs it into the grid, it will cause the grid to collapse. but it is not the truth. Trista Scheiffer, director of research and development engineer at Chevrolet Spark EV, explained why: As long as the grid is large enough to easily withstand the steady growth of demand, and most of the car's charging time is off-peak hours. With the increase in the number of households installing solar panels and large-scale solar power stations, this is even less of a problem.
As a result, power companies are likely to change their business strategies, and will not be left behind in the offensive of home solar charging devices, because manufacturers, heavy industry and other major power users have always had a huge energy demand, and plug-in cars and solar energy Home networks do not and cannot meet this need. Therefore, large-scale energy suppliers will still have a place.
Just like any technological product, competition will drive the future to develop higher performance and lower cost solar energy systems, thereby attracting more buyers and expanding the market until the sky-and-wire and coal yards have become history.
