Why is methane so expensive to harvest as a nonrenewable energy source? methane is found deep in the earth's crust, which makes it difficult to harvest. methane is found only in the mediterranean sea which makes it expensive to transport. methane is stable because it is found in sand, but must be filtered and that is expensive. methane is unstable, so harvesting it has to be done carefully, which is expensive.

Methane is unstable, so harvesting it has to be done carefully, which is expensive.

Explanation:

Methane hydrates are like fossil fuel's evil cousin. They form after bacteria breaks down organic debris, which then crystalizes under the high pressure and low temps at the bottom of the ocean. Similar to fossil fuels, these crystals burn easily, meaning they're an efficient source of energy. However, unlike fossil fuels, collecting these crystals can be tricky, and deadly, due to one small problem. They kind of explode when disturbed. That's not a big deal, right? Oh, they also easily disintegrate, causing the seafloor to become unstable and collapse, which can cause landslides. Like I said, evil cousin.
