Cities are the world’s biggest producers of fossil fuels, but they’re also the world at risk of becoming carbon-rich.
Nowhere is that more obvious than in the cities of Singapore and Singapore, where cities and their economies depend on geothermal power generation for their electricity needs.
A new study, published in the International Journal of Environmental Research and Public Health, shows how geothermal can be a sustainable way to power the world.
“It is the world where geothermal is now the main energy source and is a growing market,” said the lead author, Dr. Andrew P. Smith, professor of civil and environmental engineering at the University of South Florida.
“It is a renewable energy source that is cheap, it can be done rapidly, and it is a source of energy that is clean.
So it is an opportunity to be able to have the greatest impact on the environment.”
According to Smith, the world can benefit from geothermal in several ways.
It could be used to generate electricity in places like India, where it produces around 40 percent of the countrys electricity.
It can be used in low-income countries, like Singapore, which is home to around half the worlds population.
It also can be deployed in low demand urban areas, where the energy generated is cheaper than coal-fired power plants.
But geothermal isn’t the only energy source.
Many other technologies are being researched and used to develop renewable energy.
And many of these technologies have the potential to be deployed safely.
Smith said that is a critical point in developing a safe way to use geothermal.
“What we found is that geothermal, for example, can be applied in a safe and efficient way in areas where there is a lot of geothermal potential, and we found that even in areas like Singapore and India where there’s very little geothermal activity, we could have a significant reduction in the carbon emissions associated with geothermal,” he said.
“In the areas where we found significant reductions, it was from the water and soil that was used as the source for geothermal heat.
That is really the major driver of CO2 emissions.”
Geothermal energy has the potential of being used in a number of different places, Smith said, but for the study, he focused on areas with low geothermal emissions.
“We found that we could reduce carbon emissions by using geysers to generate a small amount of energy,” he explained.
“We found a significant amount of geyser-generated power in Singapore, a city of around 10 million people, and in a region of India where geysing is not very common.”
In Singapore, geysed is the way to generate energy by drilling holes through the ground and then releasing the water through the hole.
In India, geothermal has been used for more than a century to heat homes and businesses.
Smith explained that this method can be safe and environmentally friendly.
“For example, it doesn’t require any kind of drilling, it’s a very low-impact method of generating energy,” Smith said.
“In fact, it has been shown to be an environmentally friendly way to reduce CO2 by 30 percent.”
In fact it can also be done in places where there are limited geothermal resources, like in Singapore.
In Singapore, for instance, the government has developed a geothermal-fueled electric car to power cars.
The car is being tested and the results are promising, Smith noted.
“There are also several applications of geesers in the form of solar-generated energy, and these can be integrated into existing infrastructure,” he added.
The researchers are also developing a geysal power system that can produce power from the sun.
This system is expected to be commercially viable in a few years, Smith explained.
For the study that showed that geysering can be an efficient way to produce electricity, the researchers used the world as a test.
“As we saw, geesing was able to reduce the CO2 impact of thermal power generation in Singapore by 25 percent,” Smith explained, adding that geeses are also being used to heat residential areas in Singapore to reduce carbon footprints.
In the future, Smith hopes that the research will also be applied to developing a safer way to extract geothermal from geologic deposits.
“One of the areas of the world that we know a lot about is the potential for extracting geothermal as a resource,” Smith told The Salt.
“There are some geothermal deposits that are very promising, and there are some deposits that have not been explored yet, and that is where we can make an impact on geophysical processes and how we extract geysered resources.”
If we can be able have the best geothermal resource and also find a geesian deposit that is accessible to us, we can use the technology to make a difference in the world.
