Green-themed design

 I designed 4 green-themed images. 

That is, the 4 designs about concepts of sustainability: circular economy, renewable energy, additive manufacturing, and microgrid. 

Circular economy 

This economic model prioritizes recycling, reusing, and repurposing, with the goal of reducing consumption while sustaining economic activities. It’s a transformative approach to how we produce, consume, and dispose of products.
In traditional linear economy model, people take, make, use, and dispose of items. I'd say that the linear model is quite abusive. While in the circular economy model, people pay more attention to the environment. I'd say this model has more love in it.

Renewable Energy 

Though renewable energy sources are by no means limited to solar and wind powers, these two types are best-known, also most visible. So I designed the image resembling sun and wind turbine for this concept. 

Additive Manufacturing (AM) 

This term may sound strange. A much more popular name for additive manufacturing is 3D Printing. This emerging technology greatly reduces the production waste, makes manufacturing more sustainable. My design is depicting a 3D printer nozzle printing with filament.  

Microgrids 

It's basically micro power grids. The National Renewable Energy Laboratory (NREL) calls it Microgrids.  They are small-scale, localized energy systems.

These decentralized, local energy grids are transforming the way we power communities. The facilities can connect to or disconnect from the main power grid as desired, thus benefit the local renewable power production and paving the way towards energy independence.

My design shows the essential parts of microgrids, which are power source and connection controls.
