efficiency |
|
|
it relates to energy conversion efficiency where you aim to achieve a maximum useful output from a given input |
sustainability |
|
Any sustainable approach must take the future into account; the balance sheet shall include all aspects and impacts. The three angles to look from and at are the environment, social issues and economic considerations. The result is to always avoid any unforeseeable and irreversible burden for future generations and at the same time limit its immediate footprint on the basis of most advanced technologies and know-how. |

it's so basic |
|
Does everybody really believe mankind will be able to go on neglecting the rudimental rules of and on this globe and get away with it? Does mankind know those rules? If yes, ... then, do we really follow those? If no ... then, why wonder? |
E = mc² hence, we should have known better! |
footprint |
|
The more specific term "carbon footprint" is used to describe the greenhouse gas emissions of a product through its life span - that should include its production, raw materials, energy input, transports, etc. down to the recirculation of the spent good into appropriate recycling processes. Our fight to reduce mankind's overall footprint in order to hopefully limit global warming will soon see CO2 labels on every product and even attached to every service offered; the CO2 - and other greenhouse gasses' - value will then become part of the costing and pricing. This might become the last chance that mankind will be able to learn and acknowledge that there is a price to be paid for damaging nature. |

growth |
|
The free world societies and economies are based on "growth"; nobody questions this; the opposite, it has become the religion of the free markets, the neo-liberal bonanza, all protected by so-called democratic installations. who invented that? does anybody question this religion? who defines what growth is? who will make the planet grow? are we happy with that? who and what will help us to learn how to do better? |

when you were born... |
|
guess, how many fellow passengers lived on planet Earth when you arrived? You will hardly believe the answer. |
|
the masses arrived and consume... |

The world's population...  Human mass on the left in "billions", the years 1950 to 2050 at the bottom. The blue area refers to the industrial countries, the rest of the world's population is shown in red. When I was born we were app. 2.5 billion, 50 years later this figure has far more than doubled. With no impact? Traveling and flying then was a secret and reserved for the rich and the beautiful; while around 1900 the average travel distance per year and person added up to app. 340 miles, mostly by rail, it today sums up per person and year to app. 16.000 miles. A 50-fold increase per person, but a 200-fold increase for the planet. Again - no impact? The World's Energy Consumption in septillion BTUs, 1970 to 2025. By the way, a septillion needs 24 zeros! More on these zeros you find here.
Really, no impact? Although in German, this link might give you much more background. |

CO2 and friends |

Saving fuel and saving CO2 emissions is directly related - some figures and formulas to compare fuels and heating systems... |

Historical trends of carbon dioxide |
|
|
The thread is for real and has long arrived; we are challenging a balance that had established itself without the means of our fantastic brain power over a couple of million years. the chart It will be interesting to see us make it better. rock's forum |
The most recent geological history, in the last hundred thousand years, has been characterised by cycles of glaciations, or ice ages. The historic temperatures, through these times, have been low, and continental ice sheets have covered large parts of the world. Through ancient air, trapped in tiny bubbles in the Antarctic ice, we have been able to see what the temperature cycle was at that time, and also the concentrations of carbon dioxide (CO2). The more recent history, from the middle ages and up until now, show increasing temperatures, rising as the world emerged from the Little Ice Age (LIA), around 1850. With the industrial era, human activities have at the same time increased the level of carbon dioxide (CO2) in the atmosphere, primarily through the burning of fossil fuels. Carbon dioxide is one of the main greenhouse gases, and scientists have been able to connect human activities as one of the drivers to climate change and global warming. |

rats in a cage |
|
Put one ♀ and one ♂ rat into a big, beautiful and self contained cage; let them have food, treat them well, comfort them, supply panem et circenses, play stations and drugs, cheap transport, democratic shine and social feelings industrial lobbys and political parties, professional politicians and plebeian tribunes, and forget moral, ethics and faith. Watch! How will the experiment end? Could we learn from this experiment? What? Would we?
