Ud i landskabet 007: Energisystem uden biomasse II
Den anden af to debatter i Middelfart, som handler om at udfase biomasse og især træ i dansk fjernvarme og energiforsyning generelt.
How to Power the World 24/7 — Without Oil
9:34 | Deep beneath the Earth sits 50,000 times more energy than all the world’s fossil fuel reserves, but accessing it requires using the same controversial technology that oil companies spent trillions to develop: fracking.
13 miles down and 1000 degrees! Hot enough for you?
11:27 | There’s enough energy just in the very thin crust of our planet to run human society for hundreds of thousands of years.
Batteries are dirty. Geothermal power can help.
8:00 | In Indonesia, where the majority of nickel for lithium-ion batteries is produced, the production process emits large amounts of carbon and pollution. It doesn’t have to be this way. Indonesia sits along the Ring of Fire, one of the most geologically active regions in the world.
The untapped energy source that could power the planet
15:10 | Deep beneath your feet is a molten ball of energy the same temperature as the surface of the sun — an immense clean energy source that could power the world thousands of times over, says Jamie C. Beard.
Geothermal Energy meets Master Planned Communities : A blueprint for the future?
10:16 | A major housing development in Austin, Texas is installing five miles of geothermal pipework to serve a Master Planned Community that will comprise 7500 homes and 30,000 residents.
Geothermal ground source heat pumps. Heating your home from your own back yard!
13:35 | Geothermal energy could be potentially transformational for our power grids. But you and I can also get in on the act by drawing our own domestic heating from beneath our gardens (or communal gardens if you live in an apartment block).
Why don’t we all just use Geothermal Energy?
14:37 | Science tells us there’s enough energy in the first 10 kilometres below our planet’s surface to provide all our energy needs for millions of years. So why isn’t our entire planet powered by it?
Geotermisk energi i Danmark
5:15 | Geotermi er varme hentet op fra undergrunden. Filmen viser kort, hvordan geotermisk energi udnyttes, og hvilke muligheder, der er for at bruge den i Danmark.
