This economics essay examines the impact of the Goods and Services Tax (GST) on the battery market in India, particularly concerning electric vehicles (EVs) and solar energy storage. The essay analyzes the effects of a high GST rate (28%) on battery prices, supply, and demand, arguing that a reduction to 5% would lower prices, increase equilibrium quantity, and stimulate the EV and renewable energy sectors. It uses supply and demand diagrams to illustrate these effects, including increased producer and consumer surplus. The analysis extends to the EV market, showing how lower battery costs would reduce EV prices and increase demand. The essay also considers the impact on petrol vehicles, highlighting the competitive dynamics. The conclusion strongly advocates for a GST reduction on batteries to support India's EV and renewable energy goals, emphasizing the economic feasibility for consumers. References from economic literature support the arguments.
