Ground source heat pumps are "the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available," but maybe we can get journalists to talk about them anyway. [Repost]

If Elon Musk or some other Silicon Valley visionary proposed some laughable plan based on non-existent technology, reporters would be scheduling interviews within the hour, but a solution supported by experts based on mature, tested systems will get little to no coverage.
One of the biggest crises facing California is a failing electrical grid, particularly during summer heat waves which are going to continue becoming more frequent and severe as the planet warms. Ground source heat pumps and similar technology could greatly alleviate pressure on the grid, especially when coupled with roof top solar. On top of that, its efficiency reduces demand for fossil fuels.
If we're going solve our problems, we can't go on being disinterested in solutions.
The US Environmental Protection Agency (EPA) has called ground source heat pumps the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available. Heat pumps offer significant emission reductions potential, particularly where they are used for both heating and cooling and where the electricity is produced from renewable resources.
Ground source heat pumps are characterized by high capital costs and low operational costs compared to other HVAC systems. Their overall economic benefit depends primarily on the relative costs of electricity and fuels, which are highly variable over time and across the world. Based on recent prices, ground-source heat pumps currently have lower operational costs than any other conventional heating source almost everywhere in the world. Natural gas is the only fuel (Read more...)
