What are the four types of new energy currently available?

New energy mainly includes four types: wind energy, solar energy, biogas, and fuel cells. The basic introduction and main characteristics of new energy are as follows: Basic introduction to new energy: Also known as unconventional energy. It refers to various forms of energy other than traditional energy sources. These are energy sources that are just beginning to be developed and utilized or are being actively researched and awaiting promotion, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. Main characteristics of new energy: Abundant resources, mostly renewable, available for sustainable use by humans; low energy density, requiring large spaces for development and utilization; contains little or no carbon, with minimal environmental impact; widely distributed, conducive to small-scale decentralized use; intermittent supply, high volatility, unfavorable for continuous energy supply; currently, except for hydropower, the development and utilization costs of renewable energy are higher than those of fossil fuels.
As someone who cares about the environment, I've always believed that new energy vehicles are a great solution to air pollution. Currently, there are four main types: pure electric vehicles that run entirely on batteries, with zero emissions making them ideal for urban commuting; hybrid vehicles that combine gasoline and electricity for driving, significantly reducing fuel consumption and emissions; plug-in hybrids that can be charged externally and can run dozens of kilometers in pure electric mode after a full charge, saving money and being eco-friendly; and hydrogen fuel cell vehicles that use hydrogen to generate electricity for driving, emitting only water vapor, which is exceptionally clean. I've found that these vehicles play a huge role in reducing carbon footprints, and many countries encourage their promotion through subsidies to make them more affordable. Charging stations are increasing rapidly in cities, and home charging stations are convenient to install. The driving experience is quiet and comfortable, and in the long run, it's beneficial for both the planet and us. I hope more people will try green transportation.
