“Experts believe the ongoing Russia-Ukraine war will make countries in Asia shift toward green energy,” Scorch informed Orak, Felix, and Verum.

“How so?” Verum said.

“In February, Russia invaded its neighboring country, Ukraine. Ever since the war, global prices of oil, coal, and natural gas have increased. The countries will have to start looking for cheaper options that will also be environmentally friendly,” said Scorch.

Felix further explained, “Oil, coal, and natural gas are known as fossil fuels. They form naturally from the remains of plants, animals, and other living organisms that lived a long time ago. Fossil fuels are burned to create energy. It is used to produce electricity, fuel for vehicles, heat for buildings, etc.

But burning fossil fuels is harmful to the environment. They release harmful gasses that cause pollution. Fossil fuels are also nonrenewable resources. It means they are limited. Once they are burned, they are gone forever. We cannot renew them.

On the other hand, green energy is environmentally friendly. Green energy is energy generated from natural resources such as wind, sunlight, or water. They are renewable resources.”

“Oh, I understand now,” Verum said.

“Which green energy should the Asian countries invest in?” said Orak.

“Experts believe hydrogen will be the best energy source to help countries shift from fossil fuels to green energy,” said Scorch.

Scorch added, “South Korea, a country in Asia, is looking at hydrogen. The country wants to use hydrogen for generating power and hydrogen-powered cars.”

“How is hydrogen energy environmentally friendly?” Verum wanted to know.

“When hydrogen is consumed, only water is released. No harmful gasses are released into the atmosphere,” said Felix, “But there are different types of hydrogen such as gray, blue, and green. Green hydrogen is the cleanest hydrogen energy. It is the most environmentally friendly. Gray and blue hydrogen are not very environmentally friendly.”

“Green hydrogen is very expensive. So, South Korea is currently looking into gray and blue hydrogen. Many experts believe gray and blue hydrogen are first steps toward green hydrogen,” Scorch concluded.
