Which resource is likely to run out in the future due to overconsumption?

Natural gas is a fossil fuel that is formed over millions of years from the remains of organic matter. Its availability is limited by the amount that can be extracted from the Earth's crust. As natural gas continues to be consumed at high rates for electricity production, heating, and as an industrial feedstock, there is a significant risk of depletion. This resource is not renewable; once it is used, it cannot be replenished on a human timescale. In contrast, options like hydropower, solar energy, and wind energy are renewable resources. They utilize natural processes that can be continuously replenished, making them sustainable over the long term despite their own environmental and infrastructural challenges. Therefore, natural gas stands out as a resource that may run out in the future due to overconsumption.
