Why does New Zealand convert there green energy from Ac to dc to feed other island?

The south island usually has a surplus of power, and the north island a deficit.
The distance is several hundred kilometres, and for long distances, DC has less loss than AC.
Also, the equivalent DC voltage will be .707 of the AC voltage, thus savings in insulator costs. Similarly, the undersea cables only need to withstand a lower voltage.
The DC voltage in the cables is + 250KV and -250KV.
The current is re converted to AC in the southern part of the north island.
One of the significant problems, is that one has to convert the signal to almost pure DC, for simple rectified AC has horrendous noise radiation. And Capacitors (the usual solution to that problem) are impractical when you are dealing with Megawatts.

Green plants convert light energy from the sun into?
Chemical Energy
Photosynthesis is a process in which green plants convert to what?
Actually, the green plants don't convert TO anything in photosynthesis. Rather, they convert the light energy given off by sun light into glucose (energy).
Green plants use what kind of energy during photosynthesis?
The Green plants convert solar energy into chemical energy and with the help of cholorophyll they produse their food.
Green organisms convert energy in sunlight to energy stored in food during?
Photosynthesis
What is the process called by which green plants convert sunlight into energy?
photosynthesis
What is the process called by which green plants convert sunlight to energy?
they are called evergreen.
What enables green plants to convert light energy into chemical energy?
chloroplasts ^yes, organelles called chloroplasts which contain a green pigment named chlorophyl. Chloroplasts undergo photosynthesis, in which light excites electrons in photoreceptors and their energy is used to convert CO2 and H2O into O2 and Glucose (C6H12O6)
What is the function of green pigment in chlorophyll?
it will trap light energy from the sun and convert it into a form of energy that the plant can use during photosynthesis
Why energy stored in green plants is classified as potential energy?
The energy stored in plants is classified as potential energy because they convert light energy into chemical potential energy stored in glucose.
What are the green plasmids that trap sunlight and convert it into chemical energy in a simple sugar molecule?
The pigment containing green organelles in cells are called plastid. The plastid involved in converting chemical energy into sugar is chloroplast.
How do green plants feed?
green plants make their own food in a process called photosynthesis. Chlorophyll helps to trap energy from the sun. plants use this energy to convert water and carbon dioxide into sugars and starch.
Food making by green plants a chemical change?
The food making process in green plants is photosynthesis. During photosynthesis, plants convert light energy into chemical energy that is later released to fuel the plant's activities.
