Tidal energy uses the kinetic energy from the rising and falling of ocean tides to generate power. Hydropower is another renewable energy source that has seen wide adoption and can be used to produce electricity. Micro hydropower plants are an exciting green technology development that don’t require a dam and can be installed with minimum construction works. Offshore wind farms are also a popular renewable energy source, utilizing the wind to generate power with zero carbon emissions.
2. Water Purification
Water purification technologies are increasingly important for sustainable development as the demand for freshwater grows, and the quality of available water decreases. Some of the most promising technologies for water purification include protein nanofibrils, dual plumbing, greywater re-use, rainwater harvesting, and water conservation fixtures.
Protein nanofibrils are a recent innovation in green technology for water purification, which involve the use of diary and agricultural industry byproducts, or even food waste, to create a filter. This technology has the potential benefits of reducing waste, providing an effective filtration system, having a low carbon footprint, and being both affordable and scalable.
Dual plumbing is a water-efficient technology which lowers sewer traffic and enhances the potential of re-using water on-site. Greywater re-use is the process of using wastewater from domestic sources for other purposes, such as flushing toilets or watering plants. Rainwater harvesting involves collecting, storing, and using rainwater for multiple purposes, including agricultural and domestic use. Finally, water conservation fixtures help to reduce water consumption by using more efficient fixtures, such as low-flow toilets and showerheads.
3. Energy Efficient Buildings
There are several energy efficient building types that are used to reduce greenhouse gas emissions and promote sustainability. These types of buildings use eco-friendly materials, require minimal heating and cooling, and are designed to produce little to no carbon across their lifespan.
The first type is low-carbon buildings, which make use of designs that reduce air leakage and enable natural ventilation. They also use high-performance windows and insulation techniques, strategic window placement for day-lighting, and renewable energy sources such as solar panels.
The second type is passive houses, which are designed to use the building design itself to control the temperature. Passive houses use no mechanical or electrical devices, and are capable of saving cooling-related energy up to 90% compared to traditional building stock.
The third type is buildings that use sustainable construction technologies like wood, which is a sustainable material with a lower embodied energy compared to steel and concrete.
Finally, buildings can also make use of smart appliances to reduce energy consumption. These appliances typically include micro ovens, SmartGrid refrigerators, dishwashers, and washing machines.
Overall, these energy efficient building types can help reduce carbon emissions and promote sustainability.
4. Renewable Energy Systems
Some examples of renewable energy systems include solar panels, wind turbines, geothermal energy, tidal energy, and micro hydropower plants. Solar panels are typically used for consumer-scale energy production and work best when the sun is out. Wind turbines are used to generate energy from wind flow and can produce energy consistently for long periods. Geothermal energy harnesses heat from the Earth’s core and can be used to generate electricity. Tidal energy is generated from the ebb and flow of ocean tides and can provide a steady source of power. Finally, micro hydropower plants are an efficient and low-cost way of generating energy. These plants don’t require dams and are installed along or on the bottom of rivers and canals. They work 24/7 and require minimum space, thus making them ideal for decentralized energy production. They also have zero CO2 emissions when operating.
5. Biofuels
Biofuels are fuels derived from biomass, such as plants, algae, or agricultural waste. They are renewable sources of energy that can reduce dependence on fossil fuels and provide an environmentally friendly alternative to traditional petroleum-based fuels. Biofuels offer a number of advantages, including lower emissions of greenhouse gases and air pollutants, increased energy security, and increased economic opportunities for rural areas.
Common biofuels include biodiesel, which is made from vegetable oil, animal fats, and used cooking oil; ethanol, which is derived from corn, sugarcane, wheat, or other grains; and biogas, which is produced from landfill waste, agricultural waste, sewage, and other organic wastes. More advanced biofuel technologies are being developed to further reduce emissions, including algae-based fuels, synthetic fuels derived from biomass, and renewable diesel fuels made from biomass. These technologies promise to offer even more environmental and economic benefits than traditional biofuels.
6. Chemicals and Materials
The types of sustainable chemicals and materials are those that are naturally sourced and promote green safety standards, biodegradable materials, and low emitting materials and products. Naturally sourced chemicals and materials, such as cork, wood, and bamboo, do not contain any toxic, irritating, or carcinogenic elements and improve indoor air quality (IAQ) by limiting exposure to health-threatening chemicals. Biodegradable materials, such as sustainably sourced bamboo, timber, and mycelium, limit the negative impacts on the environment as they easily break down without releasing toxins. Low emitting materials and products are essential for today’s designs and construction, as they improve human health and protect the overall environment. They help the building projects achieve green building credits from agencies like LEED, IGBC, and GRIHA, and usually apply to a range of environmentally friendly building products, such as adhesives and paints.
