This is a non-fossil fuel Open Thread, with a suggested topic of what the World will look like in 2030.
There are many different visions of the future. Some see either slow or fast collapse due to financial crises caused by high debt levels, overpopulation, resource constraints, war, and environmental damage (not a complete list.)
Others see the potential for technological progress in EVs and other transportation, low cost solar and wind energy sources, reduced cost battery storage, low cost sensors, and new business models leading to disruptive changes that may allow us to overcome many resource constraints, reduce environmental damage, and transform society. In addition, this optimistic view foresees a Worldwide demographic transition with World population peaking in 2050 at 8.2 billion and falling back to 7 billion by 2100 and reaching 2 billion by 2200 as total fertility ratios (TFR) fall to 1.6 births per woman and average life expectancy tops out at 90 years.
Reality may fall somewhere between these sharply contrasting visions of the future, but from my perspective, the future is far from clear.
