What Is Cleantech?
Essential to clean energy is a category of companies known as “clean technology” or “cleantech.” The products and services these diverse cleantech companies provide are critical to producing, supporting and storing clean energy. As a result, the cleantech category has the potential to be a growth investment opportunity for the long term.
Clean Energy Is Becoming Essential to Meeting Energy Demands
Cleantech Could Be a Trillion-Dollar Market Opportunity
Manufacturers of wind turbines, solar panels, lithium-ion batteries, electrolyzers and fuel cells are anticipated to have an annual market opportunity rising well above $1 trillion by 2050,1 especially as dependence on oil potentially decreases. As the chart below shows, cleantech (as defined by wind, solar, batteries, electrolyzers and fuel cells) is projected to rapidly accelerate, with a significant jump in growth expected to occur by 2030—which may make cleantech a growth investment opportunity that’s here to stay.
