Renewable energy sources such as wind energy, solar energy, hydropower, and biological energy are still in the status of human auxiliary energy, and they all look like substitutes. The emergence of carbon-neutral communities will change this situation. The United States "Popular Science" magazine recently selected the world's nine most promising carbon-neutral communities, and their inspiration to humankind can be revolutionary.
Carbon neutrality saves the country
Carbon neutrality is also called carbon offset. People convert the carbon dioxide emissions produced by daily activities into economic costs, and then pay to specialized agencies to offset the corresponding amount of carbon dioxide in the atmosphere through tree planting or other environmental protection projects. The planning and construction of carbon neutral communities aims to eliminate carbon footprint.
In May 2007, a tornado struck the green town of Greensburg, Kansas. After the disaster, nearly 95% of Greensburg was razed to the ground. However, Seung Weng lost his horse and he knew he was not happy. At the time of rebuilding the home, the 900-strong town determined to use geothermal, solar and wind power to create a "green energy demonstration city." Soon, the 10-turbine wind farm outside the city began to generate power on the grid. Several buildings in the community even rely entirely on wind and solar generators to achieve energy self-sufficiency.
The community is expected to reach a carbon neutral goal by 2017, and the total annual carbon offset is equivalent to planting 825,000 trees.
If carbon neutrality is vital to the country, it is the Maldives. As long as the sea level rises by a few inches, this island nation will sink into the sea. The Maldivian people have invested the money earned from tourism into energy infrastructure construction and carbon neutralization projects, hoping to create a demonstration country for renewable energy development. The Maldivian people plan to complete this goal by 2020, reaching a target of 2 tons of carbon emissions per capita per year and a total carbon offset of 790,000 tons. If it fails, they can only consider India or Australia to buy a piece of land with high altitude.

The Maldivians want to succeed, they should learn Danish. Without the government's tax break allowance and any preferential policies, the Sangsa Island community in Denmark was named the “fastest converting†new energy demonstration site. By insisting on the use of wind energy and similar energy, the island has changed from a large coal and oil consumer to an alternative energy exporter. In addition to meeting its own needs, it produces 10% more surplus of new energy.
Parasol power generation lighting is correct
The oil-rich UAE’s capital, Abu Dhabi, responds to global warming in a cost-effective manner. It plans to build Masdar City, a future zero-carbon city, in the desert 11 miles southeast of the city, using the abundant solar energy in the desert to build the largest 10-megawatt solar farm in the Middle East. Urban designers use ingenuity in solar energy collection. They are considering building a parabolic reflector system that can collect sunlight from a central tower solar power station. In the center of the city, a large number of umbrella-shaped solar panels supported by pillars will be erected in the future. During the day, these white “small umbrellas†open up to collect sunlight while blocking the sun for the pedestrians underneath; at night, “small umbrellas†are folded and folded to become street lights that illuminate people. Since the city of Masdar is forbidden to travel by car, the city’s 50,000-person population will be dominated by light rail trams, maglev transportation systems and walking, so its daily power supply is only 1/4 of the equivalent city.
Compared with Abu Dhabi, the British are making more steady progress in carbon-neutral community planning. The United Kingdom is the pioneer of offshore wind energy in the world, and its overall utilization of wind energy ranks eighth in the world. The UK plans to achieve carbon neutrality by 2030 through wind energy development.
In the zero energy-consuming community in Bedington, London, every inch of land is designed for all-round sustainable development. The construction materials of 100 families and 15 apartments are all locally sourced. Each house is equipped with unique triple-glazed windows, solar panels, bio-fuel boilers, high-quality recycled heat insulation materials, and low-energy homes for use in every household's kitchen. Electric appliances are all equipped with high-powered meters and water meters, and the owner of the house can understand the energy consumption of the house at a glance.
