Wind energy

Wind energy is from the kinetic energy of moving air. We harness wind energy with large wind turbines located on land or in the ocean. Wind turbines are technology we got from improving the structure of good old windmills used to harvest wind power in the 18th/19th century. 

As the wind blows against the wind turbines, they generate electricity we can use for various activities. However, the wind power gained from harnessing wind energy varies by location. The best place to get enough wind power is by setting up turbines in sea or freshwater locations, i.e., offshore.

Solar energy

The sun is a major energy source. We harness this endless solar energy source with solar panels. Studies show that we get more energy from the sun in an hour than the energy used by the world in a year1. 

Solar panels are made from silicon and other materials that can transform sunlight into electricity. They can power homes, schools, and communities. Solar power is an excellent example of sustainable development because it provides safe energy consumption. 

It doesn't release carbon emissions like when we harness energy from fossil fuels. Renewable energy sources don't cause air pollution, thus saving the environment and promoting energy efficiency.

Sustainable Agriculture

The environmental impact of industrial agriculture damages a lot of ecosystems. These damages include soil erosion, groundwater pollution, air pollution, greenhouse gas emissions, and poor working conditions of farm workers. 

Since we depend on agriculture for food, the negative impacts of industrial agriculture make our survival difficult. So, we need to practice sustainable farming to get food without causing harm to the environment. 

According to the United States Department of Agriculture, sustainable agriculture is farming methods that protect the environment, expand natural resources, and use non-renewable resources adequately. 

Eco-friendly agricultural practice focuses on systems that improve soil fertility and reduce emissions and energy consumption. It also focuses on improving animal welfare and encouraging biodiversity. 

Crop rotation is one way to promote sustainable agriculture. This method improves soil quality by reducing fertilizer usage, thus restoring the lost nutrients and improving local biodiversity. Other eco-friendly agricultural practices are hydroponics and permaculture.

Green Spaces

While the previous example of sustainable development focuses on structure, green space is about open spaces in urban areas., such as foliage-filled public parks and recreation areas. 

Data says more than two-thirds of the world's population will live in cities2. It will be crowded with buildings and infrastructures to support the people, and nature needs more space to grow and thrive.

We can improve air quality by having more green spaces full of trees. Aside from producing oxygen, trees regulate rainwater by filtering out pollutants.

Addressing the urban island heat effect is also vital. This phenomenon refers to the trapped heat generated by human activities, specifically roads and other concrete structures. By adding green rooftops, people can save the energy used for cooling. 

Green spaces in urban regions  could be parks, community gardens, or rooftop gardens. These spaces help us control insects and improve biodiversity. They will also enhance the quality of living.

Sustainable Forestry

Sustainable forestry is managing forests to meet society's current needs and desires while preserving forest resources. We achieve sustainable development of forests by considering the economic, social, and ecological aspects of sustaining a forest. The three ways to manage forests are preservation, rehabilitation, and reforestation techniques. 

Preservation allows us to take necessary precautions to protect our forests from destruction, while rehabilitation and reforestation refer to replanting and replacing a lost forest ecosystem. By sustainably managing our forests, we'll have cleaner air. More trees will grow, and they'll capture carbon and clear air pollution from the atmosphere. 

Also, there will be a reduction in the loss of biodiversity because the environment supports their ecosystem. Sustainable forest management will reduce flooding because trees are a barrier to water streams. Thus slowing them down. 

Another example of sustainable forest management techniques is selective logging to prevent excessive deforestation. There's also controlled burn and treatment of tree diseases, providing better water quality for humans and wildlife.

What are SDGs?  

Sustainable development goals (SDGs) are a call to action to end poverty and inequality, protect the planet, and ensure people enjoy good health, justice, and prosperity. In a nutshell, SDGs aim to change the world without leaving anyone behind. 

In 2015, all member countries of the United Nations decided to implement the 2030 Agenda for Sustainable Development. All the examples of sustainable development above are aligned with this plan.

17 interconnected goals balance economic development, social inclusion, and environmental sustainability. Here are the 17 SDGs that need global attention and action:

No Poverty
Zero hunger
Good health and wellbeing
Quality education
Gender equality
Clean water and sanitation
Affordable and clean energy
Decent work and economic growth
Industry, innovation, and infrastructure 
Reduced inequalities
Sustainable cities and communities
Responsible consumption and production
Climate action 
Life below water
Life on land
Peace, justice, and strong institutions
Partnerships for the goals
Conclusion: All About Sustainable Development Examples, Goals, And More

The extraction and usage of raw materials like fossil fuels and poor waste disposal methods are the major contributors to the environmental decline. However, examples of sustainable development have shown that we can get essential services in environmentally friendly ways. 

For instance, renewable energy reduces greenhouse gas emissions by providing sustainable energy. Green spaces bring nature closer to people living in cities. It also protects biodiversity. Crop rotation protects soil health and improves agricultural produce, while sustainable manufacturing uses more recycled materials. 

Other examples of sustainable development include sustainable concrete and mobility, efficient lighting, and green tourism.
