How Important Is Green Energy Investment?

The financialization of green energy has proven to be an undeniable success, with both China and the U.S. emerging as global leaders in attracting capital to fuel the energy sector's transformation. China, in particular, has been remarkably successful, with a staggering $546 billion in green energy investments in 2022, while the U.S. trailed behind with $141 billion.

Moreover, renewable energy has undergone a remarkable transformation. Once deemed costly and risky, heavily subsidized, it has become more affordable than certain traditional fossil fuel sources. Developments in mitigating intermittency issues and energy storage have played an equally pivotal role in this transformation and have raised the possibility that renewables could become the primary electricity source in the next 20-30 years.

The Latest Trends in Green Technology

The eco-friendly solutions like electric vehicles and solar power which once considered niche or unconventional, have now gained mainstream acceptance as part of the collective effort to combat climate change. The Climate Tech 2020 Report, published by PwC, highlighted a massive shift in investment trends. In 2013, venture capital investments in decarbonization solutions amounted to $418 million, but this figure soared to an impressive $16.1 billion in 2019. Subsequently, the momentum continued, with an exceptional $87.5 billion invested in climate tech between July 2020 and July 2021, as reported in the Climate Tech 2021 Report.

Corporations have undergone an equally pertinent evolution in their corporate responsibility initiatives, placing a much stronger emphasis on sustainability. For instance, Alphabet Inc (NASDAQ:GOOG) has taken notable steps to address climate change which is also evident in the eco-routing feature of Google Maps, that has already resulted in a reduction of over 500,000 metric tons of greenhouse gas emissions.

Similarly, Apple Inc (NASDAQ:AAPL) has made pertinent contributions in reducing its carbon footprint in its operations and is actively working towards a carbon-neutral goal by the year 2030. Apple Inc (NASDAQ:AAPL) also encourages its suppliers to adopt clean energy practices. Through their Power for Impact program, Apple Inc (NASDAQ:AAPL) is dedicated to facilitating access to clean energy for communities worldwide. Apple Inc (NASDAQ:AAPL) is considered one of the greenest tech companies.

Moreover, green hydrogen is emerging as a leading force in the clean energy transition and has gained a significant traction and recognition as the energy of the future. In 2023, numerous major green hydrogen projects are set to reach final investment decisions or commence construction, which signifies a shift from theoretical discussions to large-scale reality.

The momentum behind green hydrogen is further amplified by a surge of government subsidy schemes worldwide. The US hydrogen tax credits alone offer up to $3 per kilogram of green hydrogen to producers and promise substantial support. Additionally, the EU and UK Contracts for Difference subsidy programs and Germany's H2Global scheme will also provide financial assistance for clean hydrogen imports.

Digital technology, particularly Artificial Internet of Things (AIoT), also plays a crucial role in accelerating the transition to green hydrogen. The World Economic Forum suggests that AIoT-enabled solutions can cut capital and operating expenses by up to 25%, expediting the commercial viability of green hydrogen by four to seven years. As investments rise and government backing strengthens, the future of green hydrogen is undoubtedly promising.

Clean Energy Projects in the US

In August 2022, the US enacted the Inflation Reduction Act of 2022 to curb inflation, reduce the budget deficit, and invest in domestic clean energy production. According to a report by Climate Power, Georgia ranks second in the U.S. for new private-sector clean energy projects since the Inflation Reduction Act's passage, with 22 projects and 16,678 expected jobs. Michigan leads with 24 projects, while Kansas expects 20,600 jobs. The law has been praised for boosting green energy investments and driving development. However, Governor Brian Kemp criticized the law for having little impact on EV and battery manufacturing expansion.
