Geothermal energy taps into and harvests the heat released from below the surface of the earth. It’s a renewable energy that doesn’t contribute to greenhouse gas emissions. Geothermal energy reduces our carbon footprint and doesn’t take up a structural footprint, either. Unlike the endless fields of wind turbines or solar panel arrays, most of the energy generation happens out of sight and underground.
The idea behind controlling waterways through dams isn’t new. The oldest dam in the world, the Kallanai Dam, began operation on the Kaveri River in Tamil Nadu, India in the 2nd century, and it’s still in use today.
Climate change and the future of our planet are increasingly concerning topics, but tackling the issue of preserving the environment can seem overwhelming to any one person. However, we all have the capability to help prevent the effects of climate change through the types of energy that we choose to use.
Traditional energy sources like oil, natural gas, and coal contribute to pollution, but renewable energy offers a practical alternative that could reduce the impact we have on the environment every day.
Ignorance is a very, very bad thing. Last week, as North America suffering from extreme cold weather because of a phenomenon called “polar vortex“, Jim Hoft, founder of the American far-right news and opinion website The Gateway Pundit has tweeted that: “It’s a bit cold outside this morning in middle America… Aren’t you glad you aren’t heating your home with a solar panel like nitwit socialist @AOC is demanding?” (@AOC is the American politician and activist Alexandria Ocasio-Cortez here.) What Jim Hoft says is flat-out wrong. Solar panels DO work in the cold. They work by absorbing LIGHT from the sun, not heat.
In the quest for expanding the boundaries of human exploration and ensuring the long-term survival of our species, the idea of colonizing Mars and other celestial bodies has emerged as a captivating and viable possibility. While Earth remains our home, the potential colonization of Mars, along with other planets and moons within our solar system, presents a host of compelling reasons. From scientific discovery and resource utilization to the preservation of our species, the case for venturing beyond our blue planet grows increasingly enticing.
