Task1. Listen to the audio clip to complete the passage with proper expressions.
Electricity storage, electricity storage systems are the set of _________1____________ used to store electricity. The need for electricity storage is due to an __________2___________ in supply and demand on the electrical grid due __________3___________ to an increase in renewable energy generation. These supply and demand ________4_____________occur because renewables are _________5____________, meaning electricity isn't produced when the sun isn't shining or the wind isn't blowing, even though consumers still require electricity in these renewable __________6___________. Currently, grids distribute electricity in _________7____________, meaning electricity is being consistently produced to meet consumer demand. Electricity storage gives grid operators the flexibility to use electricity that otherwise would be wasted. This grid flexibility is highly sought after and has the potential to ___________8__________ how we produce and consume electricity, and is therefore being widely researched and tested. There are many different forms of electricity storage, the most common being: battery, pumped hydro,_________9____________, and ___________10__________. Currently, the largest challenges in implementing electricity storage at the grid scale are the cost and the infancy of the technology. That's electricity storage.
