Earth Day 2020 is the 50th Anniversary of Earth Day.

Earth Day 2020Earth Day 2020 is the 50th Anniversary of Earth Day although unfortunately, the world is facing global sustainability issues such as COVID 19, climate change, and other issues.
Achieving sustainability is a work in progress and calls for a constant evolution of technologies, ideas, and concepts to develop solutions that are practical and effective. Sustainability solutions will be resilient and focused on overcoming technical and policy barriers that prevent the uptake of sustainability in different sectors of society.

As of today, the world is experiencing some of the pressing global challenges that we probably have not experienced in our lifetimes. Clearly, technology will not or does not provide all the answers that we need today, however, it will help to speed up or assist in moving us towards a sustainable path. Technological solutions are just one part of the big picture as other solutions include policy, regulations, sustainable business as well as innovative financing options that are effective to promote sustainability from a systems’ perspective.

Technology can be broadly defined as the entities, both material and conceptual created by the application of mental and physical effort to achieve some value. Technological change, on the other hand, can refer to several yet compatible concepts involving an improvement in technology or technological progress. According to Rogers (2003), the idea of technological change underpins a social process involving adopters and others who are profoundly affected by its cultural setting, political institutions, and marketing strategies.

Sustainability calls for new concepts and ideas to reverse, for instance, the effects of climate change. Solar photovoltaics (PV) is just one of many of the new technologies to help in sustainability efforts. IRENA notes that renewables such as solar PV and energy efficiency offer a safe, reliable, and affordable way to achieve massive decarbonization in line with keeping the rise in global temperatures “well below 2°C”. IRENA’s analysis shows the combination of renewables, energy efficiency and increased electrification could achieve 90% of the reductions needed in energy-related emissions.

Renewables are also becoming cost-effective and with time we have seen for example solar power at grid parity. Grid parity is the point when the cost of alternative energy becomes equal to or less than electricity from conventional energy forms like fossil fuels. As such, renewable energy subsidies are now been phased out, and, in the USA for instance, the investment tax credit (ITC) to support consumers in switching to solar was reduced at the beginning of this year from 30% to 26%.

Now, the solar investment tax credit is available to homeowners in some form through 2021. In 2020 & 2021 owners of new residential and commercial solar can deduct 26% or 22% of the cost of the system from their taxes respectively. The ITC will then be reduced to 10% available for only owners of new commercial solar energy systems while there will be no federal credit for residential solar energy systems’.

Furthermore, IRENA’s analysis of renewable energy shows that the cost of electricity from renewable energy technologies has fallen steadily and even dramatically in recent years, and since 2000, especially for solar and wind generation and are now seen as viable commercial options. Also, power generation from renewable sources and technologies has become competitive with fossil-based or nuclear power.

Food waste is another issue that has become a huge sustainability issue over the last decade. In particular, food waste is a major source of methane (CH4) which is one of the most potent gases that is causing climate change. If food waste were a country, it would come in third after the United States and China in terms of impact on global warming. Hence, reducing food waste around the world would help curb emissions of planet-warming gases, lessening some of the impacts of climate change such as more extreme weather and rising seas.

With these sustainability challenges, it is clear that Earth Day 2020 presents us with an opportunity to contribute to efforts of fighting sustainability issues facing planet Earth and there so many solutions as we have captured above.
