Over the course of 125 years green energy has seen transformations that have advanced with technology research that have driven changes and revolutions in the green industry. The first major green tech was researched, developed and put into use in the 1801-1900 time period.
19th Century Green Technologies include:
- Biomass Combustion
- Geothermal Power & Heat
These 19th century renewable energy technologies from the industrial revolution are still in use today and have created an incredible amount of jobs and careers for people. Jobs and careers are still available today in green tech that was researched, invented and deployed in the 19th to 20th centuries.
The next phase of green energy technology was created out of the oil crisis that occured in 1973 and 1979. It was this crisis in energy that spawned heavy investments into research of green tech and renewable energy theories. More focus in the 1980′s drove the final stages of development of many of the green technologies you see today popping up.
20th Century Green Technologies include:
A majority of green degrees, certifications, training and classes are focused around the second generation (20th century) green technologies. There are a lot of new technologies on the horizon that are being researched and funded for an eventual mass market release. Most of these 21st Century Green Technologies are in their infant stage and require more funding, research and development.
21st Century Green Technologies include:
- Biomass Gasification
- Biorefinery Technologies
- Concentrating Solar Thermal Power
- Hot Dry Rock Geothermal Energy
- Ocean Energy
- Nanotechnology Green Tech
