ریت کی بیٹری قابل تجدید توانائی، گھریلو ہیٹ پمپس اور سولر پینلز کی معاشیات کو ذخیرہ کرتی ہے۔

کے اس پرکرن میں فزکس ورلڈ ویکلی podcast, we meet Markku Ylönen, who is co-founder and chief technology officer of the Finnish company پولر نائٹ انرجی. The firm has created a “sand battery” that stores excess renewable energy as heat, and can be used to smooth out variations in supply that occur when the Sun isn’t shining and the wind isn’t blowing.

Ylönen is in conversation with طبیعیات کی دنیا’s Margaret Harris, who has also written a خصوصیت مضمون about how installing a heat pump and solar panels can reduce domestic energy consumption from mains sources. In this podcast she talks about the economics of these technologies and what governments can do to encourage their uptake.
