2021's Best Renewable Energy Stocks to Invest In

Updated: Mar 17

Why should you divest from fossil fuels and invest in renewable energy?

Since the industrial revolution, humanity has gone from muscle power and biomass burning for energy to fossil fuels (coal, oil, and gas). The burning of fossil fuels has been the main force behind the rapid development of technology and economies, but it has come at the cost of an increase in atmospheric carbon dioxide and air pollution.

As a solution to this global issue, there has been a push to change direction from fossil fuels to renewable energy. And, according to Forbes, the value of oil, gas, and coal reserves is set to drop due to the rise in government climate and energy security targets. This is paired with a higher risk of investing in fossil fuel caused by clean technologies (cleantech) competition.

The cleantech competition includes renewable energies such as wind, solar, hydro, and geothermal energy. The Australian Renewable Energy Agency defines renewable energy as energy that is:

“produced using natural resources that are constantly replaced and never run out.”

Renewable energy also creates a dramatically smaller carbon footprint compared to its predecessor, fossil fuels.

Is renewable energy a good investment choice?

The energy in Australia is changing with a growing interest in renewable energy. Due to government policy incentives, elevated electricity prices, and a decline in renewable generation technology costs, the market for renewable energy has seen a dramatic increase in investments. The graph above shows a steady increase in renewable energy sources for electricity generation.

As reported by the Responsible Investment Association Australasia (RIAA), investors have seen an average annualised return of 5.1% in GSS bonds and 11.3% in public equity across 2018 and 2019. For comparison, investments in positive social outcomes were recorded as being 4.4% p.a. while the investments in environmental outcomes were at 5.5% for 2018 and 2019.

Moreover, RIAA also discovered that 92% of impact investors have either had their financial expectations met (66%) or exceeded (26%). And with 90% of respondents believing that impact investing has a significant future in the stock market, the next question should be where to look.
