What You'll Learn
Switch to renewable energy sources
Fossil fuels, such as coal, oil, and gas, are the largest contributors to global warming and climate change, accounting for over 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. To mitigate their impact, we must transition to alternative, renewable energy sources.
Renewable energy sources are naturally replenished and abundant, including solar, wind, water, waste, and geothermal heat. These sources emit little to no greenhouse gases or pollutants, helping to address climate change and air pollution. Solar energy, for instance, is growing faster than any other energy source, with its share of electricity generation expected to increase from just under 3% currently to 40% by 2035. Similarly, wind energy has already supplied over 45% of Texas's total energy demand on multiple occasions.
Transitioning to renewable energy sources also brings economic benefits. Renewable energy technologies can save customers money as they displace emissions from fossil fuels. Additionally, every dollar invested in renewables creates three times more jobs than in the fossil fuel industry. The transition to net-zero emissions is expected to result in a net gain of 9 million jobs in the clean energy sector by 2030.
However, challenges exist in integrating renewable energy into the electric grid due to its variable nature. To address this, grid managers are focusing on flexibility and predictability, which are lacking in large fossil fuel and nuclear plants. While renewable energy production varies, it is predictable, as we can generally anticipate sunny or windy periods.
To accelerate the transition to renewable energy, individuals can advocate for policies that prioritize renewable energy development and support initiatives that promote energy efficiency and conservation.

Reduce vehicle emissions
Greenhouse gas (GHG) emissions from transportation account for about 28% of total US greenhouse gas emissions, making transportation the largest contributor to US GHG emissions. Therefore, reducing vehicle emissions is crucial in the fight against global warming and pollution.
One way to reduce vehicle emissions is to switch to electric vehicles or other low-carbon fuel alternatives. Electric vehicles do not burn fossil fuels like gasoline and diesel, which release carbon dioxide, a greenhouse gas, into the atmosphere. While electric vehicles may not be suitable or affordable for everyone, there are other options, such as hybrid models and compact fuel-efficient gas vehicles, that can also help reduce emissions. Additionally, when purchasing a new car, individuals can look for fuel-efficient vehicles with low greenhouse gas emissions, such as cleaner-burning gasoline vehicles. The EPA's Green Vehicle Guide and Fuel Economy and Environment Label can help consumers compare different vehicle models and choose the most fuel-efficient and environmentally friendly option.
Another way to reduce vehicle emissions is to improve fuel efficiency in existing vehicles. Properly inflating tires, regular maintenance, and removing unnecessary accessories from the car roof can all help increase fuel efficiency. According to the EPA, if all Americans kept their tires properly inflated, we could save 1.2 billion gallons of gas each year.
Reducing the number of vehicle miles traveled is also crucial in cutting vehicle emissions. Individuals can choose to walk, bike, or use public transportation whenever possible. Carpooling and choosing to live in walkable cities and towns with quality public transportation can also help reduce the number of vehicles on the road and, consequently, vehicle emissions.
Finally, idling vehicles contribute significantly to air pollution and waste fuel. Modern vehicles do not require "warming up" in the winter, so individuals should avoid turning on the engine until they are ready to drive. Reducing idling, especially in diesel school buses, can help prevent children from being exposed to diesel exhaust, reduce greenhouse gas emissions, and save money on fuel.

Improve energy efficiency
Improving energy efficiency is a vital and often undervalued way to reduce the greenhouse gas emissions that drive the climate crisis. Energy efficiency measures are a win-win for consumers and the broader public, as they lower energy bills and reduce pollution.
Energy efficiency is about using less energy to achieve the same result. For example, energy-efficient homes and buildings use less energy to heat, cool, and run appliances and electronics. This can be achieved through a variety of means, such as:
- Replacing outdated heating and cooling systems with newer, more energy-efficient models.
- Upgrading windows and adding insulation to attics and walls to prevent air from escaping or coming into the house.
- Investing in energy-efficient appliances, such as heat pumps, which can both heat and cool spaces.
- Using renewable energy sources like solar, wind, and hydropower.
- Making outdoor changes, such as rooftop gardens, cool roofs, and sustainable landscaping.
According to the International Energy Agency, energy efficiency could deliver a reduction in annual energy-related emissions of 3.5 Gt CO2-eq (12%) compared to 2017 levels, playing a crucial role in achieving global climate targets.
Additionally, heavy industry, which is responsible for a significant portion of GHG emissions, can also improve its energy efficiency. Decarbonizing industrial processes can sharply reduce climate emissions and local pollution.

Reduce, reuse, recycle
Reducing consumption, reusing products, and recycling waste are three key ways individuals can help combat global warming and pollution.
Reduce
Reducing the amount of material consumption is an effective way to save natural resources, protect the environment, and save money. This is because the production of new items emits greenhouse gases, requires a lot of energy, and contributes to climate change. For example, the production of basic chemicals, iron and steel, cement, aluminium, glass, and paper are among the most carbon-intensive industrial processes. By reducing the demand for these products, we can help lower the emissions and pollution associated with their manufacturing.
Reuse
Reusing products instead of throwing them away is another way to reduce waste and emissions. This can be as simple as donating unused clothing, electronics, and building materials to ensure others can make use of them. Maintaining and repairing items also helps extend their lifespan, reducing the need for frequent replacements.
Recycle
Recycling waste products helps to limit the use of raw materials and reduces waste sent to landfills. While some materials are challenging to recycle, such as plastic bags and electronics, many everyday items can be recycled, including plastic, paper, batteries, and electronics. Recycling helps curb greenhouse gas emissions and plays a practical role in limiting the climate crisis. For example, Project Drawdown estimates that recycling between 2020 and 2050 will reduce emissions by 5.5 to 6.02 gigatons of carbon dioxide, which is equivalent to taking over one billion cars off the road for a year.
By adopting these "three R's": reduce, reuse, and recycle, individuals can make a significant collective impact in the fight against global warming and pollution.
