The importance of reducing emissions

The primary goal of renewable energy policies is to reduce greenhouse gas emissions, which are the leading cause of global warming. By increasing the share of renewables in the global energy mix, we can significantly decrease harmful pollutants released into the atmosphere.

This can help mitigate the adverse effects of climate change, such as rising sea levels, extreme weather events, and biodiversity loss.

Moreover, adopting climate policies contributes to sustainable development and security. By diversifying the energy mix, countries can become more resilient to fluctuations in energy prices and reduce dependence on imported fuels.

Furthermore, the transition to renewable sources can create new employment opportunities, stimulate economic growth, and improve public health by reducing air pollution.

As we delve deeper into the various policies, it becomes clear that continued investment and international cooperation are essential to ensuring a greener, more sustainable future.

Types of green energy policies

To reduce carbon emissions and promote clean energy, various policies have been put in place by governments and organisations worldwide.

These policies encourage renewable energy production, technological innovation, and financial investment in the green energy sector.

This section will discuss four popular renewable energy policies: Feed-in Tariffs (FITs), Renewable Portfolio Standards (RPS), Green Certificates, and Net Metering.

Illustration showing the varying types of policies designed to incentivise green energy uptake.

Feed-in tariffs (FITS)

Feed-in Tariffs (FITs) are financial incentives offered to energy producers who generate electricity from renewable sources such as solar, wind, hydro, and biomass.

Under this policy, the government guarantees a fixed price per kilowatt-hour (kWh) for renewable energy fed into the grid. This price is typically higher than the market price for electricity, making it an attractive proposition for renewable energy investors and producers.

The primary objective of FITs is to encourage investment in renewable energy projects by providing a stable and predictable income stream for producers.

This policy has successfully driven the energy transition in countries like Germany and Spain, where FITs have significantly increased renewable energy capacity.

Renewable portfolio standards (RPS)

Renewable Portfolio Standards (RPS) are regulatory policies that require electricity providers to supply a specified percentage of their power from renewable sources.

This policy aims to diversify the energy mix, reduce dependency on fossil fuels, and promote the growth of the renewable energy industry.

Under RPS, electricity providers can either generate the required renewable energy or purchase Renewable Energy Certificates (RECs) from other renewable energy producers.

This creates a market for RECs, which helps to drive investment and competition in the renewable energy sector. RPS policies have been widely adopted in the United States, with 29 states and the District of Columbia implementing such standards.

Green certificates

Green Certificates are also known as Renewable Energy Certificates (RECs) or Guarantees of Origin (GOs). They are tradable commodities representing the environmental attributes of electricity generated from renewable energy sources.

These certificates can be bought and sold separately from the physical electricity, allowing electricity providers to meet their renewable energy obligations, as required by policies such as Renewable Portfolio Standards.

The Green Certificate system helps create a market for renewable energy, encouraging investment and promoting the sector’s growth. Additionally, it allows consumers to choose renewable energy and contribute to a greener future.

Net metering

Net Metering is a billing arrangement that allows owners of renewable energy systems, such as solar panels or wind turbines, to receive credit for any excess electricity they generate and feed back into the grid.

Under this policy, the electricity meter tracks the difference between the electricity consumed and the electricity generated by the renewable energy system.

When the system generates more power than it consumes, the excess electricity is fed into the grid, and the owner receives a credit against their electricity bill.

Net Metering encourages the adoption of renewable energy technologies by reducing the cost of ownership for consumers. It also helps the electricity sector to manage demand and promotes energy independence.

Net Metering policies have been implemented in various countries, including the United States, Canada, and Australia.

Renewable energy policies around the world

Europe
