I find the course to be valuable. Video lectures were engaging and very good quality. Practice examples and quizzes were pointed and relevant. The consequence of all this is that I learned a great deal about global warming and gained valuable insights about what we can, and should do to curb some of it's negative impacts. Otherwise, the consequences of inaction is far too great.

Nice course, not only for learning English, also to be familiar with causes and effects of Climate Change in our world, and the new sources for creating renewable energy.

Uau !! Adorei fazer esse curso. Foi uma experiência muito empolgante. Quero fazer outros. Não me sentia preparado , ou estava com medo de não dar conta, mas a partir da 3ª semana comecei a ler com mais autonomia os textos e entender os áudios. Foi uma ótima experiência que tive e aprendi muito. Esse mês de janeiro não possuo recurso para pagar o certificado mas gostaria de comprar o curso mais para frente se for possível. Realmente estou encantado com a plataforma.

I've not used MOOC for a long time as well as English, so I took this course as my comeback bufferin. It fulfilled my purpose as the the English taught here is clear and without stress (you can speed up the video whenever you want), to add to that it taught me a lot of knowledge about climate change and scientific findings new to me. The citing skills and reference standards are things I'd always wanted to learn. All in all, it's of great help to me.

I would like to express my gratitude to Coursera and Penn University that give me useful lessons to improve my learning skills and upgrade more knowledge in the fields for my future.

It was good course. Great concepts of emerging science. Reading and Writing Scientific literature was impressive.

I have learned a lot about climate change and improved my English

This is a great course, will asked my family member to enroll

This corse was amazing thank you so much

very useful, for life, for job, for all

Well constructed course for beginners.

Excellent technical information!

not received my certificate

Super

good

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.^[1][2]

It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules(EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.^[3][4]

I am very grateful to the teachers Alyssa Swanson and Jack Sullivan for this excellent course!

All the material presented in the course is the highest quality, the explanations are clear and understandable, all videos are provided with a review of learning the material, all the tasks are perfectly prepared. In addition, most importantly - the relevance and importance of materials and the positive attitude of teachers! Made cool! Thank you very march.

I really enjoyed the course. All steps including videos and practice readings were useful. I learned the impact of climate change and how human could contribute in reducing the release of carbon dioxide into the atmosphere. I learned great on nanotechnology and how scientists are involved in testing new materials to increase the renewable energy system. And how new discoveries will change the human life across the world. Thank you!

Fue muy gratificante y reflexivo este curso, para tomar conciencia de que nuestro planeta nos necesita, y tenemos que usar los recursos naturales de manera responsable, porque los que primero sentimos las consecuencias del cambio climático, somos nosotros mismos. Gracias al generoso pueblo norteamericano,que a través de sus autoridades, nos brindan la oportunidad de tomar estos cursos para desarrollarnos como mejores personas.

This course, I thought, was very well put together. The facilitators were phenomenal and were great in their delivery of all information related to this course.

Unfortunately, I did not put as much time as required for this course as I would have loved to even though I manged to complete it.

I feel this course was a good intro for me having been away from Coursera school for "many moons".

As a audio learner, I much appreciated the use of technology in the class in conjunction to discussing ,readings and presentation projects. I think it's one of the most progressive lit courses I’ve ever taken between the somewhat unknown readings and way of instruction. I feel like my writing has not only improved by my mind is more open.

My name is Jose Antonio from Brazil. I am looking for a new Data Scientist career (https://www.linkedin.com/in/joseantonio11)

I did this course to complete my CV in English to the area of Data Science. 


The course was excellent and the classes well taught by teachers.

Congratulations to Coursera team and Instructors.

Regards.

Jose Antonio.

it's really an interested courses i have ever gotten. i understand all about climate change and global warming etc ; now i am able to distinguish between notions and vocabularies related on climate afterwards i learned almost all pioneering and promising methods to create clean an renewable energy. It's really outstanding !

Thank you for this graduating this course. It is timely as part of my classroom teaching. The Global warming theme is such timely to teach now to educate my students about their part in alleviating this global warming trend. Once again, thank you so much to my instructors: Mr. Jack Sullivan and Miss Alyssa Swanson.

It is one great English course in which grammar is given within the course's content! I think the course is also good for advanced learner's as it reviews grammar points, gets in touch with the American English (for the ones who has been studying the British and Aussie variations), learns new skills!
