Answer the following questions related to the text.

Read the text above and answer whether the statements are true or false.

a) The sun is our most important source of energy.

b) It could provide all the energy needed by a modern industrial so­ciety worldwide for the indefinite future; which "conventional" energy source could do.

c) In the 1970s, there was widespread enthusiasm, and a genuine grassroots movement emerged in the U. S. in anticipation of an imminent transition to an economy based on the nuclear energy.

d), New solar technologies could easily have supplied a double-digit percentage of energy used by now.

e) It was/is the prime example of confluence, rather than conflict, of environmental and economic wellness.

0 Expensive, high-grade focusing devices could have been avail­able by easy mass-production in the 70s.

g) That is not to say that working for SE can be dangerous.

a) What is the sun for our life?

b) What could the sun provide for the mankind nowadays?

c) When and why was a widespread enthusiasm concerning solar energy?

d) What is the main key to serious direct solar energy?

e) What are the problems associated with solar progress?

1) When were all the components of the plant developed?

2) What technology do the new units use?

3) What is the name of the new plant?

4) What does the new design provide?

This project has supported the construction of a PVpower plant, which is the first of its type in the world. All the components of the plant were developed during the previous projects and now, in this latest project, the size of the concentrators has been increased to full commercial di­mensions. These new, modular units consist of two 75 metres long rows of PV cells. The new units use reflecting instead of refracting technolo­gy, have single-axis tracking and encapsulated modules.

The new plant, named EUCLIDES, has eight units, each with two rows of concentrators 72 metres long and 2.9 metres wide. The two rows in each unit share a single tracking carriage. Each unit is rated at 62 kWp, giving a total rating of 480 kWp. Each tracker has an output of 750 V. In the concentrator units themselves, the cells are interconnected and en­capsulated, just like flat modules, and the concentration of optics are mir­rors instead of the Fresnsel lenses used in all previous PV units.

The new design provides a more constant output than that from flat panels, and this means that a better price should be obtained for the electricity produced.
