This is a great course on energy technologies, with quite in-depth lectures on the technologies, current research, future prospect and delivered by experts in their field of study. The assignments were also interesting, and tailored to inspire what you can do to be more energy efficient and explore your local surroundings on existing or future initiatives on sustainability. I'd recommend this course to anyone interested to know the current and future energy and renewable technologies, or aspiring researchers to explore and zoom in their field of interest. Great job!

excellent course, learned a lot

This is an outstanding course which covers such a wide range of energies including wind solar, and a large variety of bio-fuels. I was impressed with the selection of different presenters who were all specialists in their field. The level of technical detail is appropriate for a layman while being quite in depth. In fact in some cases one might feel overwhelmed but this was intended in order to give a good feeling of the innovative technologies, problems and futures. It was good to review the well known energy sources like nuclear, hydro, fracking, corn ethanol, etc, but I would say most people are unaware of all these alternative sources of energy such as from various plants, algae to make bio-fuels or electricity.

The questionnaires were both helpful in forcing one to pay sufficient attention even if sometimes they are near impossible to get 20 on 20. Also I thought the interviews were especially well prepared and helpful to recall the basic material presented. Bravo

An excellent course that covers all aspects of modern energy challenges. Definitely recommend!

good course with detailed information. I enjoyed by part of this.

Me encanta, ojalá pudiera pagar por obtener el certificado :(

Very informative course even for someone with a prior knowledge in a particular segment in renewable energy. Covers diverse energy resources along with economic, and environmental considerations.

Toca perfectamente las temáticas para desarrollar un futuro enfocado en energías renovables , aspectos desde económicos, físicos, científicos, politicos con el actual sistema de energía y las repercusiones que conlleva el manejo inadecuado de los recursos así como los efectos de la contaminación en el mundo.

Excellent teachers, thanks to you all.

Dr. Stephen Mayfield inspire respect for the subject, Congrats!

I appreciate the fact that the course addressed not only the technical details of each of the most promising technologies that are being developed in the energy sector but also the socioeconomic and political issues that we need to face in order to make a meaningful dent in the negative impact humanity has on the world.

Great learning experience! Easy way to get an idea of the work that is being done to better our lives in the future in terms of energy. Very interesting lectures and would highly recommend it.

Me gusto mucísimo el curso. 90% de la información es nueva para mí y sé que la aprovecharé para desarrollar una idea que tengo para crear mi propia empresa que sea ambientalmente amigable

This is the first course that I have done on Coursera and I have to write: it has exceeded my expectations, It have give me tools to go forward in my studies about energy. I'm waiting for a course with updates about this subject!

Extremely interesting, well organized course. Highly recommended!

Excelente, gracias

It is Amazing!!!!

Muy buen curso, incluso para los que no tienen mucha idea del tema, como yo. Me ha abierto mucho los ojos para los problemas derivados de los combustibles fósiles, pero también me ha dado mucha esperanza por la gran variedad de alternativas que ya disponemos para enfrentar el reto del desarrollo sostenible.

Very knowledgeable.......very informative

Very good, informative course. A broad field of science is included, from biotech to sociology, and lots of information. Recommended!

Great course in order to understand that energy solutions are as with many other things, a trade-off. There is no either-or solution.

best course in the world!

you must take this course if you want to know basicly about energy past, present, future

It gives great insight into biofuel production, but also how other renewable energies work, and the necessity of them coming together to cope with global energy demand :)

This course is an excellent introduction to energy topics especially in the optic of the energy challenge that humanity faces with global warming!

Excellent course. I learned a lot. Thank You UCSD!
