Renewable energy from wind turbines and solar photovoltaic panels has become the cheapest source of new electrical generation across most of the world. ----. When wind speeds drop or thick clouds obscure the sun, electrical output fluctuates rapidly, necessitating large-scale grid energy storage batteries or dispatchable backup power.
- A)Therefore, international governments have banned all further construction of wind farms
- B)Moreover, solar panels generate identical electrical current regardless of whether it is day or night
- C)Consequently, coal-fired power stations have become the preferred choice for green environmentalists
- D)In contrast, electricity cannot be transmitted over high-voltage copper power lines safely
- E)However, the fundamental challenge confronting green energy grids is their weather-dependent intermittency
