Want a World Without Blackouts? Power the Future With Renewable Energy.

Want a World Without Blackouts? Power the Future With Renewable Energy. 86

Renewable and Sustainable

Whether at the national or corporate level, an integral part of most plans to combat climate change is making the shift to renewable energy sources. With solar and wind power leading the charge, renewables are steadily finding their way into the energy infrastructure of a number of countries and companies. Some have already become 100 percent renewable, while others continue to carefully wean themselves from fossil fuel.

There is, however, a sizable hurdle that early renewable energy adapters will inevitably encounter. Energy output from solar and wind, and to a lesser extent hydrogen, are dependent on circumstances beyond human control. An emerging solution to this issue is the use of energy storage devices or commercial-grade batteries like Tesla’s Powerpack.

A new study from Stanford University and the University of California, Berkeley (UCB) argues that this hurdle could very well be overcome by a combination of solutions. By making renewable energy completely reliable, it could provide consistent power across all sectors, potentially making blackouts a thing of the past. A manuscript of the study has been published in the journal Renewable Energy.

Lead author Mark Jacobson, a civil and environmental engineering professor at Stanford, also lead a recent study that presented a roadmap to 100 percent renewable energy dependence for 139 nations. In the new study, the researchers completed the roadmap, suggesting three scenarios that would maximize renewable energy output and sustain power to supply the grid.

Three Solutions

Using a combination of computer modeling programs that can predict global weather patterns from 2050 to 2054, Jacobson and his colleagues constructed scenarios where 139 nations, grouped into 20 world regions, had converted all sectors into renewable energy by 2050. The team also factored in the effect on energy output from solar and wind power sources. Using another model, the team then calculated the energy produced by more stable renewable sources, such as geothermal and hydrogen.

“One of the biggest challenges facing energy systems based entirely on clean, zero-emission wind, water and solar power is to match supply and demand with near-perfect reliability at reasonable cost,” co-author Mark Delucchi, a UCB research scientist, said in a statement. “Our work shows that this can be accomplished, in almost all countries of the world, with established technologies.”

The results described three scenarios in which nations struck a proper balance between energy output from renewables and predicted energy demand for 2050. Of note, in all three scenarios, blackouts at low energy costs were avoided for a five-year period. The researchers noted that having various energy storage options available was an important factor in that outcome.

For the 20 regions in CASE A, concentrated solar power (CSP) storage, batteries and thermal energy storage proved to be crucial — however, the study noted that “no hydropower turbines beyond current capacity or heat pumps were added.”

Similarly, the 20 regions in CASE B, also found that thermal energy storage and CSP-with-storage were key; the only difference was the addition of hydropower turbines. Though, the study noted that these didn’t increase annual hydrogen power output.

In the third scenario — CASE C — things played out a little differently. CSP and commercial grade batteries were the dominant energy storage options for the regions in the scenario (14 instead of 20),  but no hydropower turbines were included. However, the study noted that “heat pumps with no storage replaced all cold and low-temperature heat thermal energy storage.”

Jacobson summarized the results of the study, saying:

Our main result is that there are multiple solutions to the problem. This is important because the greatest barrier to the large-scale implementation of clean renewable energy is people’s perception that it’s too hard to keep the lights on with random wind and solar output.

Jacobson also noted that an important consideration for all three scenarios, in terms of creating a roadmap that works, is political cooperation between the 139 nations. That probably doesn’t come as a surprise, though — considering how clean energy programs and climate deals often depend quite heavily on the politics of the nations involved.

“Ideally, you’d have cooperation in deciding where you’re going to put the wind farms, where you’re going to put the solar panels, where you’re going to put the battery storage,” Jacobson explained. “The whole system is most efficient when it is planned ahead of time as opposed to done one piece at a time.”

Having a road-tested roadmap, so to speak, should at the very least help guide these nations — and the researchers hope they’ll be confident to take action sooner rather than later. If warnings about the rate of global warming are to be heeded, we need a stable renewable energy infrastructure in place well before 2050.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 91

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 92

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 93

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
