What’s green tech?

Green tech is ecologically friendly based on its production process or supply chain. A “green technology” acronym can also apply to renewable energy generation, alternative fuels, and environmentally friendly technologies.

Due to growing awareness of climate change and natural resource depletion, the green technology sector is young but attracting investors.

Understanding Green Tech

Green technology is the application of science and technology to make eco-friendly products and services. Green tech is similar to clean tech, which focuses on improving operational effectiveness while lowering expenses, energy consumption, waste, and environmental impact.

Green technology protects the environment, repairs past harm, and conserves natural resources. Green technology has also increased and drawn significant investment.

A business division or firm may aim to adopt green technology. Environmental, sustainability, and governance (ESG) or mission statements often articulate these aims. More socially conscious investors focus on firms that use or manufacture green technology.

President Joe Biden signed the $1.2 trillion Infrastructure Investment and Jobs Act on November 15, 2021, allocating significant funds for green tech. The most excellent investment in clean energy transmission and E.V. infrastructure in history, electrifying thousands of school and transit vehicles nationwide, and forming a new authority to develop a robust, clean electric grid are examples.

History of Green Tech

Green tech is fashionable now, yet some corporate methods date back to the Industrial Revolution. Since the early 19th century, experts have studied the environmental impact of coal-burning industrial facilities. Manufacturers have improved manufacturing techniques to decrease soot and waste byproducts.

World War II was a significant event in the U.S. Over 400,000 volunteers collected metal, paper, rubber, and other commodities for the war effort to minimize consumption and waste.

Scientists like Rachel Carson warned of chemical pesticides’ effects after the war, while physicians abroad reported inexplicable nuclear radiation-related diseases. Many credit this age with launching the ecology movement, which tried to protect ecosystems and resources while raising awareness of runaway technology.

The government slowly realized the need for environmental protection. Over the next few decades, curbside recycling programs raised household garbage awareness. The 1970-founded Environmental Protection Agency mandated coal scrubbers and other clean technology and imposed strict pollution and waste standards.

World War II saw the first extensive U.S. recycling program. Over half a million people recycled tens of thousands of tons of garbage during the conflict.

Types of Green Tech

Green technology includes several environmental remediation methods. Although climate change and carbon emissions are global concerns, numerous efforts are underway to address local environmental threats. Some safeguard habitats or endangered species. Others explore sustainable ways to save precious natural resources.

Alternative Energy

Many companies are developing carbon-free energy alternatives to replace fossil fuels. Solar and wind power are increasingly economical, with solar panels accessible to U.S. residents. Not yet scaled up are geothermal and tidal energy.

Electrical Vehicles

According to the EPA, transportation accounts for over a third of U.S. greenhouse gas emissions. Many automakers are considering fuel-efficient engines or switching to electric power to cut pollution.

However, electric cars require many advancements, such as high-capacity rechargeable batteries and charging infrastructure. Many power grids still use fossil fuels, limiting electric car benefits.

Sustainable Farming

Farming and livestock have a significant environmental impact, from land and water expenditures to pesticides, fertilizers, and animal waste. Thus, agriculture offers several green technology options. Organic farming reduces soil fatigue, cow feed improvements reduce methane emissions, and meat replacements reduce animal consumption.

Recycling

Recycling conserves precious resources by reusing or developing sustainable alternatives. Recycling plastic, glass, paper, and metal is the most common, but more advanced methods may recover valuable raw materials from e-waste or vehicle parts.

Carbon Capture

Carbon capture technologies are experimental methods for removing and sequestering greenhouse gases during combustion or in the atmosphere. The fossil fuel business has advertised this technology, but it hasn’t delivered. Though small relative to emissions, the most extensive carbon capture system can absorb 4,000 tons of CO2 annually.

Adopting Green Tech

While green technology is diverse and complex, several forms have garnered widespread adoption. Several countries are working to eradicate single-use plastics, which would require significant expenditures in paper replacements, bioplastics, and recycling technology. Singapore aims for 70% recycling by 2030.

With fossil fuels contributing to climate change, renewable energy is another green tech frontier. In 2021, 70% of new energy capacity came from solar and wind power, according to the Energy Information Administration. Investment in all renewable energy sources topped $300 billion in 2020.

Special Considerations

Green technologies aim to preserve biodiversity and save resources, yet few can do so without harming the environment. Reducing environmental expenses in one area may harm another.

Lithium is typically strip-mined from South American rainforests for electric car batteries. Hydroelectric dams emit little carbon but harm salmon and other river wildlife. Diesel-powered mining gear is necessary to harvest rare minerals for green energy devices like solar panels and wind turbines.

Green technology is not a lost cause but requires rigorous accounting to guarantee that the benefits balance the expenses.

Which green energy is the cheapest?

The International Energy Agency says solar electricity is the cheapest alternative energy. The Agency reported in its 2020 World Outlook Report that photovoltaic solar energy is “consistently cheaper than new coal- or gas-fired power plants in most countries, and solar projects now offer some of the lowest-cost electricity ever seen.”

How do I invest in green technology?

Green tech investing is simple for firms that are heavily investing in environmentally friendly technologies. Investors can choose individual companies or buy a mutual fund, index fund, or other product that reflects the environmental investing market. Instead of focusing on one business, the latter method gives investors diverse exposure to the green tech market.

Nuclear Power—Green?

Nuclear power is contentious, and many scientists question its merits. Fission-derived nuclear power creates highly radioactive waste that must be kept for thousands of years yet provides reliable, economical electricity without greenhouse gases. Chornobyl and Fukushima have strengthened campaigners’ claims that nuclear power is unsafe. However, nuclear accidents kill fewer people than fossil fuel pollution.
