Finance
The discount rate is the interest rate used in financial analysis to calculate the present value of future cash flows. In renewable energy investing, it reflects the required rate of return or the cost of capital for a project. A higher discount rate indicates greater perceived risk or return expectation, which reduces the present value of future project cash flows (making the project less attractive). Investors use the discount rate in metrics like Net Present Value (NPV) and to compare investment opportunities, adjusting for time and risk.
