This paper states why energy insecurity is a problem in Indonesia‚ how it was identified‚ its causes and the current responses to solve this problem. The engineering solutions would focus on sustainability and affordability‚ without compromising future generation energy needs in Indonesia. International Energy Agency defines energy security as the “uninterrupted availability of energy sources at affordable prices”. Currently Indonesia faces the lack of long term energy security. This is evident

the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific heat capacity) x temperature change = energy transferred

Increase the momentum of the object over a long time 8. Most street barriers are made of hard rubber or plastic materials that easily give in or dent when hit. Why is this so? A. To reduce the vehicle’s kinetic energy when it collides with the barriers B. To store potential energy in the bumpers of vehicles C. To reduce the impact force when hit by a vehicle D. To reduce the impact time when the barriers hit the vehicle 9. What is the momentum of a 20 kilogram cart moving

Solar Energy Outline: Abstract Recently‚ the solar energy technology market has experienced phenomenal growth. Due to growing public awareness of environmental issues‚ clean energy research funding has increased. This funding increase has created dramatic technological improvements. Compared with traditional energy‚ solar energy is showing many remarkable advantages. Despite its technical and economic limitations in the present‚ it is expected that solar energy will play an important role in

Group Project Homework: Ch 1 page 28 10) Although forces in the foreign environment are the same as those in the domestic environment‚ they operate differently. Why is this so? The concept of forces in business should affect the foreign and domestic environment the same‚ but in actuality the forces in the two environments act differently. First the values of differing countries can create rifts in businesses around the world. Many incidents occur where a country will place an embargo on another

In this simple exercise you will measure how much work you do and calculate how powerful you are. Safety You will need some stairs that you can safely run up‚ preferable more than one floor. Normally‚ you shouldn’t run on stairs. So you should • not run up stairs if you are sick or have a medical problem • check that your teacher

Potential and Kinetic Energy Transformations Potential and kinetic energy can be found in things all around us‚ especially in roller coasters. Potential energy is stored energy in an object‚ and kinetic energy is energy of motion or speed. On a rollercoaster it can switch from potential to kinetic energy very often. The rollercoaster starts off with a chain and motor and exerts a force on the rollercoaster which pushes the ride to the top of the hill. Throughout the process of going up the hill

Renewable energy‚ a source of energy that holds a significant promise to help reduce the amount of toxins that are by-product of too much energy use and bring a positive impact on our planet that we currently use as our source of energy.These include energy from water(Hydropower)‚ wind‚ the sun(solar power)‚ geothermal sources‚ and biomass fuel. In contrast‚ fuels such as coal‚ oil‚ and natural gas are non-renewable‚it’s finite and will some day run out completely. One of the most common renewable

Alternative Energy Sources Fossil fuels will not last forever. If the human race wishes to continue to live the way we do‚ then we have to look at alternative energy sources such as: geothermal‚ nuclear‚ solar‚ wind‚ and hydroelectric energy. Alternative energy sources are not without faults‚ but along with faults‚ there are benefits and solutions to the issues. Geothermal energy is a well-proven energy resource that can be used to provide both heat and electricity. Geothermal energy is very predictable
