Forecasted Developments for CleanTech

Globally, the investment toward carbon free energy is on a steep upward trajectory. In 2023, this investment almost doubled to around $1.77 trillion, compared to $934 billion three years prior in 2020. Alongside this surge in investment, there has been significant growth in tech venture capital funding in climate tech, which reached $70.1 billion in 2022. Indicating a rising demand for clean technologies worldwide, particularly in the Western Hemisphere.

According to the NRDC, seven out of ten Americans support prioritizing alternative energy sources over expanding fossil fuels. This widespread support underscores a societal shift towards cleaner energy solutions. As businesses adapt to this changing landscape, there are profound implications for the economy and people's daily lives. Embracing clean energy technologies not only addresses climate emergencies but also presents significant economic opportunities for businesses.

Roberto Bocca, Head of the World Economic Forum’s Centre for Energy and Materials, emphasizes the urgency of accelerating the clean energy transition. However, he notes that current investment levels are insufficient compared to the scale and pace of change needed. Unlocking financing for clean energy initiatives presents not only a crucial first step toward a secure and equitable energy system but also a clear opportunity for businesses. This shift is particularly relevant as emerging economies, representing a substantial portion of the global population, increasingly prioritize clean energy solutions.

Overall, accelerating the clean energy transition signifies a pathway towards affordable and sustainable energy solutions. Businesses can leverage this shift to not only meet sustainability objectives but also to provide cost-effective clean energy options, particularly beneficial for developing markets where affordability is crucial.

New Clean Technologies and Their Top Innovators 

Since the impact of economic growth and it fueling innovation in the industry is now established, what exactly are those innovations? This paragraph is supposed to go beyond typical buzzwords like Sustainability and Renewable Energy. Instead, we will try to introduce you to other relevant industry-driven topics, that are gaining traffic, but are not too prevalent in the public eye. All while giving credit to companies, who are the top innovators in their field.   

So, let's take a closer look at very promising technological trends.   

Solar Energy

Solar Energy, often praised as one of the most abundant and sustainable sources of power, derives from the sun's radiation. This renewable energy form has gained increasing attention as societies worldwide seek cleaner alternatives to traditional fossil fuels. Using this technology involves capturing sunlight and converting it into usable electricity. Offering a promising avenue for decreasing climate change and reducing dependency on non-renewable energy sources. 

But how exactly is Solar Energy generated? When sunlight strikes a solar panel, photovoltaic (PV) cells within the panel absorb the energy. This energy triggers the movement of electrical charges within the cells, generating an electric current. Labelled as the photovoltaic effect, this enables solar panels to convert sunlight directly into electricity. But in order to function, solar panels require proper installation in areas with enough sunlight exposure and access to necessary equipment such as inverters and batteries for storing excess energy.
