Systems that rely on renewable energy are less expensive to operate and maintain than those that use fossil fuels. Furthermore, the declining costs of energy storage systems and renewable technologies improve their long-term economic feasibility.

Renewable Energy Support Mechanisms

Feed-in Tariffs (FITs)

Put-in tariffs (FITs) are policy tools that guarantee energy producers payment for the electricity they create and put into the grid, thereby promoting the use of renewable energy sources. Renewable energy projects benefit financially from these payments, which are usually given for a set length of time and are above market rates.

How FITs Work:

• Guaranteed Payments: In a feed-in tariff (FIT) system, producers of renewable energy are paid a fixed amount for each kilowatt-hour (kWh) of electricity they produce, independent of changes in the market.
• Long-Term Contracts: Investors benefit from stability and predictability as FITs frequently have long-term contracts (10–20 years, for example).
• Differentiated Rates: Payments may differ according to the renewable energy source (solar, wind, biomass, etc.), installation size, location, and technological maturity, among other variables.

Benefits:

• Investment Security: By lowering financial risks through long-term contracts and guaranteed payments, renewable energy projects attract investment.
• Market Entry: FITs reduce the entrance barriers for smaller producers, such as individuals and neighborhood initiatives.
• Rapid Deployment: FITs can hasten the adoption of renewable energy technologies by offering financial incentives.

Challenges:

• Cost to Consumers: Higher electricity prices are usually the result of passing on the costs of FITs to customers.
• Market Distortion: By offering set rates that do not accurately represent current market conditions, FITs have the potential to distort the electricity markets.

Renewable Portfolio Standards (RPS)

Regulations known as Renewable Portfolio Standards (RPS) force utilities to guarantee that a predetermined portion of the power they sell originates from renewable sources. The goal of these criteria is to gradually raise both the output and consumption of renewable energy.

How RPS Works:

• Target Setting: RPS targets are set by governments and often represent a proportion of overall electricity sales, such as 20% by 2025.
• Compliance Mechanisms: In order to reach these goals, utilities must either produce their own renewable energy, buy it from others, or purchase renewable energy credits (RECs), which are certificates attesting to the production of renewable energy.
• Penalties for Non-Compliance: In the event that utilities do not comply with RPS regulations, they may be subject to monetary fines or other legal repercussions.

Benefits:

• Market Growth: The demand for renewable energy is stimulated by RPS rules, which also encourage investment and innovation in the industry.
• Flexibility: Utilities are free to select the most economical method of achieving RPS requirements, be it by buying RECs or making direct investments in renewable energy projects.
• Environmental Impact: RPS regulations contribute to a decrease in greenhouse gas emissions and a reduction in reliance on fossil fuels by raising the share of renewable energy.

• Implementation Complexity: Strong regulatory structures and monitoring systems are needed to set and enforce RPS targets.
• Cost Considerations: Consumers may pay more for electricity as a result of the costs incurred in complying with the RPS.

Net Metering Programs

Through the use of net metering systems, customers that produce their own electricity from renewable resources (like solar panels) can feed extra power back into the grid. They essentially lower their overall energy costs as a result of receiving credits on their electricity bills.

How Net Metering Works:

• Metering System: A bi-directional meter counts the energy generated and returned to the grid in addition to the energy taken from it.
• Billing Credits: For the extra electricity they produce, consumers are credited. When their renewable systems aren't generating enough power, these credits can help cover the cost of the electricity they need from the grid.
• Balance Carryover: Excess credits can be carried over to subsequent billing periods in a lot of net metering programs, usually within a year.

Benefits:

• Consumer Empowerment: By encouraging investments in renewable energy systems, net metering increases resilience and energy independence for consumers.
• Grid Support: Distributed renewable energy systems can contribute to grid stabilization and support by supplying extra power into the system.
• Economic Savings: By allowing consumers to get bill credits, renewable energy investments become more fiscally feasible.

Challenges:

• Grid Management: Excessive dispersed generation can make it difficult to maintain grid stability and control, particularly when it comes to balancing supply and demand.
• Equity Issues: Wealthier consumers who can buy renewable energy systems may benefit from net metering programs more than others, which raises questions regarding equity and cost distribution.
