Energy from sources that can be regenerated or reused is called renewable energy.
Renewable energy is energy that can be replenished on a human timescale like hydro-electric power, solar energy and wind power. Geothermal energy is also considered renewable energy.
Answer:
A PrintWriter reference variable named output that references a PrintWriter object is as follows:

PrintWriter output = new PrintWriter("output.txt");
The statement that writes the string "Hello World" to the file output is as follows:

Explanation:
Answer:
$2.40
Explanation:
the unit electricity bill is kilo watt hour.
The 60-watt light bulb has a 400 hour life expectency means it will consume
60×400/1000 = 24 KWh units of electricity. Let us suppose each unit of electricity costs is 10 cents.
Then 24×10 = 240 cents = $2.40
Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
